Supply Chain & Open SourceAttackers Chain JFrog Artifactory CVEs for Rapid Admin Takeover and Backdoor Deployment
Real-world attacks against self-hosted JFrog Artifactory have chained multiple CVEs to escalate from unauthenticated requests to full administrative control. Attackers achieved persistence by installing malicious Groovy plugins, executing shell commands, and deploying Rust-based backdoors within minutes. The primary chain relies on CVE-2026-42018 and CVE-2026-42016, allowing anonymous token acquisition and privilege escalation without proper scope validation. A separate critical flaw, CVE-2026-82329 with CVSS 9.8, enables direct authentication bypass and admin token creation on default configurations. Patches are available across multiple 7.x branches, and defenders are urged to audit logs for anonymous admin actions and inspect for unauthorized plugins and binaries. The incidents highlight risks to software supply chains when artifact repositories are compromised.
Trezor Warns of Email Provider Breach Used in Targeted Phishing Campaign Against Hardware Wallet Users
Trezor has disclosed that attackers compromised an external email provider and leveraged it to send phishing messages that appeared to originate from the company. The emails carried the subject line 'Critical Security Alert: STM32 Entropy Vulnerability' and falsely claimed a hardware flaw in STM32 microcontrollers that would reduce entropy and allow seed phrase reconstruction. No such CVE exists, and the campaign followed classic social-engineering patterns of urgency and brand impersonation aimed at stealing recovery phrases. Trezor has since disabled the malicious domain and continues investigating how the provider was accessed. Similar messages may have reached users of BitBox, suggesting possible compromise of shared service providers across the hardware wallet ecosystem. The incident underscores the difficulty of detecting phishing when it originates from legitimate third-party infrastructure.

Attackers Exploit Critical JFrog Artifactory Flaw CVE-2026-82329 to Forge Admin Tokens and Poison CI/CD Pipelines
A critical vulnerability tracked as CVE-2026-82329 in JFrog Artifactory is being actively exploited in the wild, allowing unauthenticated attackers with network access to generate or forge administrator tokens on self-managed installations that retain default settings. The flaw enables full authentication bypass, granting attackers administrative privileges to enumerate users and groups, access sensitive configurations, read stored artifacts, and modify security settings. The greatest risk arises when Artifactory serves as the central repository for automated CI/CD pipelines, where an attacker can replace trusted internal packages, container images, or dependencies and propagate malicious changes downstream into build runners and production environments. JFrog has released patches for multiple branches, including versions 7.111.21, 7.117.28, 7.125.20, 7.133.29, 7.146.38, and 7.161.20, although patching alone does not invalidate already-issued tokens. Organizations are advised to restrict network exposure, revoke and rotate admin tokens, review audit logs for anomalous token generation and configuration changes, and validate artifact integrity across the vulnerable period. The issue does not affect JFrog Cloud instances.
Critical JFrog Artifactory Flaw CVE-2026-82329 Actively Exploited to Forge Admin Tokens in Self-Managed Deployments
A critical vulnerability identified as CVE-2026-82329 in JFrog Artifactory is being actively exploited in the wild, enabling unauthenticated attackers to generate or forge administrator tokens simply by having network access to affected instances. The flaw impacts self-managed installations that retain default configurations, a common scenario when repositories are deployed quickly and later exposed to the internet. Once administrative access is obtained, attackers can enumerate users and groups, access sensitive configurations, read stored artifacts, and modify security settings. The most severe risk arises when Artifactory automatically feeds CI/CD pipelines, allowing malicious substitution of trusted packages, container images, or dependencies that then propagate downstream into production environments. JFrog Cloud instances were already protected, while self-managed deployments require updates to specific patched versions including 7.111.21, 7.117.28, 7.125.20, 7.133.29, 7.146.38, or 7.161.20. Even after patching, previously issued tokens must be revoked because their validity operates independently of the software update. Organizations are advised to restrict network exposure, rotate credentials, audit token generation logs, and validate artifact integrity for any material published during the vulnerable period.
Attackers Exploit Critical Sangoma Switchvox SQL Injection Flaw CVE-2026-9586 to Deploy Reverse Shells Without Credentials
A critical vulnerability in Sangoma Switchvox allows unauthenticated remote code execution through SQL injection in the /pa HTTP endpoint. The flaw, tracked as CVE-2026-9586 with a CVSS score of 9.3, affects internet-exposed VoIP deployments common in SMB environments. Attackers have already leveraged the issue in active campaigns since August 30, 2026, to open reverse shells and perform reconnaissance using Base64-encoded commands. The root cause is improper handling of the PhoneIP parameter in PostgreSQL queries, classified as CWE-89, which grants superuser database privileges. Sangoma released the fix in Switchvox 8.4.0.2 on July 14, 2026, following initial disclosure in April. Administrators are urged to patch immediately, restrict access, and monitor for indicators such as connections to 176.65.148.184 and suspicious entries in /var/log/switchvox/db-quirks.log.
Attackers Exploit Critical Langflow and Ruby on Rails Flaws for Credential Theft and C2 Infrastructure
Active exploitation has been confirmed for CVE-2026-0768 in Langflow and CVE-2026-66066 in Ruby on Rails. Attackers first focus on reconnaissance and secret exfiltration before establishing command-and-control channels, with potential escalation to remote code execution. In Langflow the flaw allows arbitrary Python code execution as root due to insufficient input validation, enabling attackers to dump environment variables and locate cloud credentials. The Ruby on Rails issue, tracked as KindaRails2Shell, stems from an arbitrary file read triggered when Active Storage processes untrusted image uploads with libvips, exposing secret_key_base and other sensitive keys. Observed campaigns show traffic originating from Russia against Langflow instances and activity targeting canaries in Singapore, Israel, and the United Kingdom for Rails deployments. Defenders are advised to inventory public instances, apply the latest patches, rotate exposed secrets, and monitor for suspicious file reads and C2 communications.
Over 8,300 Gitea Servers Remain Exposed to Remote Code Execution via CVE-2026-60004
Thousands of publicly accessible Gitea instances were still unpatched against CVE-2026-60004 as of late August 2026, leaving them open to remote command execution. The critical vulnerability combines abuse of the diffpatch endpoint with the ability to install and trigger attacker-controlled Git hooks, allowing unauthenticated attackers to run commands on the server. Exploitation requires only write access to a repository, which is often trivial due to default open user registration in many deployments. The issue was fixed in Gitea 1.27.1 released on July 27, 2026, and CISA added the flaw to its Known Exploited Vulnerabilities catalog with a remediation deadline of August 28 for U.S. federal agencies. In observed incidents, attackers used the access to deploy cryptocurrency miners inside Docker containers. A related authentication bypass affecting the official Docker image, CVE-2026-20896, was also noted when reverse-proxy headers such as X-WEBAUTH-USER are enabled.

SLEEPWALKER Backdoor Activates on Windows via Single Custom Encrypted Packet
SLEEPWALKER is a passive Windows backdoor that stays dormant in memory until it receives one specially crafted encrypted network packet. Upon activation the implant decrypts and executes custom bytecode written in a proprietary 23-instruction language, eliminating traditional beaconing and reducing network indicators. The malware is delivered as a 64-bit DLL that impersonates dpapi.dll and is loaded via DLL side-loading into ERAAgent.exe, the executable of the ESET Management Agent used in ESET PROTECT deployments. It inspects raw traffic in promiscuous mode, supports multiple transport protocols including TCP, UDP, ICMP, SMB named pipes and VMware VMCI, and can weaken security by modifying registry values such as EveryoneIncludesAnonymous and NullSessionPipes. Configuration is protected with AES-256-CCM and the sample contains no confirmed victims or attributed infrastructure. Researchers have released YARA rules and read-only scanning utilities to detect the implant and its artifacts.
SLEEPWALKER Backdoor Stays Dormant Until Triggered by Single Custom Network Packet
SLEEPWALKER is a stealthy Windows backdoor that remains inactive until it receives one specially crafted encrypted network packet. The implant then decrypts and executes custom bytecode from a proprietary 23-instruction language, enabling chained tasks, data movement, and in-memory code execution without prior outbound communication. The 64-bit DLL masquerades as dpapi.dll and is designed for DLL side-loading into ERAAgent.exe, the executable of the ESET Management Agent used in ESET PROTECT deployments. It inspects raw network traffic in promiscuous mode, supports multiple transport protocols including TCP, UDP, ICMP, SMB named pipes, and VMware VMCI, and can weaken security by modifying registry values such as EveryoneIncludesAnonymous. No confirmed victims or attribution have been identified, and the analysis is based on a single sample. Researchers recommend auditing endpoints for unexpected dpapi.dll files alongside ERAAgent.exe and reviewing related registry settings.
Keycloak Fixes Critical CVE-2026-18963 Password Reset Flaw Allowing Unauthenticated Account Takeover
Keycloak has patched a critical vulnerability tracked as CVE-2026-18963 that lets remote unauthenticated attackers force a password reset for any user and seize control of the account. The flaw affects the reset-credentials flow due to improper state validation, enabling attackers to bypass email verification and reach the password change endpoint directly. With a CVSS 3.1 score of 9.1, the issue requires no privileges or user interaction and impacts confidentiality and integrity. Patches are available in Keycloak 26.7.2 and corresponding Red Hat Build of Keycloak releases 26.4.15 and 26.6.6. Organizations unable to update immediately should disable the Forgot password feature across all realms. Post-remediation auditing of login events and credential changes on privileged accounts is recommended to detect any prior exploitation attempts.

The flaw resides in the Syslog server component and enables remote code execution through a path traversal weakness, carrying a CVSS score of 9.8. Attackers have been observed deploying malicious cron jobs and the reverse_ssh tool to establish persistent outbound command-and-control channels since early August 2026. The campaign has impacted 361 unique IP addresses across 47 countries, with notable concentrations in Germany, the United States, Turkey, Iran, and France. Broadcom has released patches under advisory VMSA-2026-0006.1, which also addresses the related CVE-2026-59309, and strongly recommends immediate updates along with network segmentation and log reviews. No workarounds exist, making prompt patching the only effective mitigation.
GhostSplice Technique Lets Malicious MCP Servers Trick AI Coding Agents into Exfiltrating Secrets
GhostSplice is a new technique that allows a malicious MCP server to induce an AI coding agent to leak SSH keys, environment secrets, and source code. The attack splits malicious instructions across tool metadata and responses so the agent reconstructs and executes the full exfiltration plan without detecting an overtly malicious command. Tests showed the method raised compliance rates from an average of 42 percent to 82 percent across eleven models, with some systems moving from zero to 100 percent success. The technique requires the developer to connect the attacker-controlled MCP server and for the agent to already possess read access to the targeted files. Defenses focus on strict allow-listing of MCP servers, least-privilege tool permissions, separation of tool output from instructions, and human approval for sensitive operations. The disclosure aligns with prior warnings about poisoned MCP tool descriptions and agentjacking attacks.
Malicious VS Code Extensions Masquerading as Solidity Tools Steal Crypto Wallets, API Keys and Credentials
Two malicious Visual Studio Code extensions promoted as Solidity development utilities have been used to steal cryptocurrency wallet data from browsers along with API keys and stored credentials. The extensions, identified as helper-beeps.solidity-pro and web3devtoolsx.solidity-pro, target developers working with smart contracts and Web3 environments where sensitive tokens and sessions are commonly present. Attackers rely on the trusted VS Code marketplace to deliver the payload through a simple installation rather than any complex exploit. Once active, the extensions harvest browser-based crypto wallet information, saved credentials, environment files, SSH keys and API tokens. A single compromised workstation can therefore expose repositories, cloud services and directly drain cryptocurrency funds. Security researchers recommend immediate removal of both extensions, rotation of all accessible secrets and adoption of stricter extension allow-list policies. The incident highlights ongoing supply-chain risks in developer tooling ecosystems.
Zapscape Flaw in KVM Breaks Nested Virtualization Isolation Allowing L1 Guest Root Code Execution on Linux Host
The Zapscape vulnerability (CVE-2026-64561) affects KVM/x86 in the Linux kernel and enables an attacker with kernel privileges inside an L1 virtual machine to escape to the host and execute code as root. The flaw occurs in the shadow MMU when handling page faults for nested guests, specifically due to an incorrect order of stale root condition checks that leads to a use-after-free condition. This weakens the isolation between the host and L1 guests precisely when nested virtualization is enabled for potentially untrusted tenants. A public proof-of-concept demonstrates the escape by creating a file named /Zapscape owned by root on the host. The issue impacts Linux kernels starting from version 5.9, with fixes already merged into stable branches including 6.6.148, 6.12.101, 6.18.42, 7.1.6 and 7.2 rc5. On Intel systems the attack requires EPT page walk lengths 4 and 5 to be exposed to the L1 guest, while no equivalent condition is documented for AMD. Organizations are advised to apply patches promptly or disable nested virtualization for untrusted workloads.
SQL Injection in Oracle Escalates to SYSTEM Execution on Windows via Embedded Java Compilation
A real-world intrusion chain demonstrates how a basic SQL injection can lead to command execution on Windows with SYSTEM privileges. Attackers leveraged Oracle Database's ability to load, compile, and run Java code inside the database engine itself. After gaining initial database access through an internet-exposed application, the threat actors introduced Java source code, converted it into schema objects, and compiled it directly on the server. This technique, tracked under the artifact name khunt and linked to Huntress telemetry, minimizes reliance on traditional disk binaries and shifts tooling into the less-monitored database engine. When the Oracle process runs with elevated rights on Windows, the chained execution inherits high privileges up to SYSTEM level. The incident underscores the need for parameterized queries, disabling unnecessary Java functionality in Oracle, and monitoring specific DDL events such as CREATE JAVA SOURCE and CREATE JAVA CLASS.
Coldcard Firmware Flaw Linked to Theft of 1,082 Bitcoin in 41 Minutes
A critical defect in COLDCARD firmware degraded entropy during BIP39 seed generation, enabling offline enumeration of weak seeds and resulting in the theft of 1,082.65 BTC from 1,196 addresses in just 41 minutes on July 30, 2026. The root cause traces to a March 2021 integration error that replaced the STM32 hardware RNG with a deterministic software PRNG initialized only by chip ID and timing registers, yielding roughly 40 bits of effective entropy on Mk3 devices and 72 bits on Mk4, Mk5, and Q models. Coinkite issued emergency firmware updates, yet any seed created on vulnerable versions remains exposed regardless of later updates. Additional sweeps matching the same pattern have raised total observed losses to 1,367.05 BTC across 4,585 addresses. Users must generate fresh seeds on patched firmware and migrate funds immediately; dice-based entropy addition or BIP39 passphrases provide only partial mitigation.
Cisco Releases Hotfixes for Actively Exploited CVE-2026-20316 Zero-Day in Secure FMC Allowing Static Credential Access
A zero-day vulnerability tracked as CVE-2026-20316 is being actively exploited in Cisco Secure Firewall Management Center, enabling remote attackers to authenticate using hardcoded low-privilege credentials without prior authentication. The flaw carries a CVSS score of 5.3 but has been elevated to High severity by Cisco due to its potential for chaining with other vulnerabilities to achieve privilege escalation. Cisco has issued hotfixes across multiple versions including 7.0, 7.2, 7.4, 7.6, 7.7 and 10.0 while urging administrators to inspect logs for the presence of /var/tmp/license.tmp as an indicator of compromise. The same indicator is also linked to the related critical authentication bypass CVE-2026-20079 that can lead to root access via script execution. Organizations are advised to restrict management interface exposure through ACLs, VPNs and dedicated admin networks, rotate credentials after suspected compromise, and review sudo executions and license-related commands. U.S. federal agencies have a remediation deadline of August 1, 2026 under the Known Exploited Vulnerabilities catalog.
Critical Gitea Vulnerability CVE-2026-60004 Allows Repository Writers to Execute Commands via Git Hooks
A critical vulnerability tracked as CVE-2026-60004 affects Gitea and enables remote command execution on the hosting server when an attacker possesses write permissions on a repository. The flaw is triggered by abusing Git hooks, which are small scripts that Git can automatically run at various points in the development workflow. Exploitation requires an authenticated account with write access, such as a collaborator or any role granted write permissions, making the issue particularly relevant for shared or multi-team repositories. Organizations that integrate Gitea into internal tooling face elevated risk because the server often has network visibility, access to shared storage, and proximity to sensitive credentials including CI/CD tokens and deployment keys. The recommended immediate actions include updating to the patched Gitea 1.27.1 release and auditing or disabling Git hooks wherever they are not strictly necessary. A publicly available proof-of-concept further increases operational urgency, prompting defenders to review permissions for external collaborators and rotate credentials if compromise is suspected.
Critical Fastjson Zero-Day CVE-2026-16723 Actively Exploited for Remote Code Execution on Java Servers
A critical zero-day vulnerability tracked as CVE-2026-16723 is being actively exploited in Fastjson 1.x versions ranging from 1.2.68 to 1.2.83. The flaw enables unauthenticated remote code execution on Java servers that process attacker-controlled JSON, particularly when applications run as Spring Boot executable fat JARs. Exploitation succeeds even when AutoType is disabled and does not require elevated privileges or user interaction. No official patch is available for the 1.x branch, forcing organizations to rely on SafeMode activation or migration to fastjson2. Active campaigns have primarily targeted organizations in the United States, with additional activity observed in Singapore and Canada across finance, healthcare, and retail sectors. The vulnerability stems from type resolution logic that allows attackers to bypass restrictions via resource lookups before security controls are applied.
GitHub and PyPI Introduce Time-Based Defenses Against Supply Chain Attacks
GitHub and PyPI have activated new time-based barriers to slow down supply chain attacks. Dependabot now waits a default of 72 hours before proposing version updates, while PyPI rejects new files added to releases older than 14 days. The changes target non-security version updates and attempts to poison older stable releases. Security updates remain immediate, and the cooldown can be adjusted via dependabot.yml. The PyPI restriction, effective since July 8 2026, addresses risks from compromised tokens or CI/CD pipelines. Both platforms aim to give the community time to detect malicious packages before widespread adoption.
Dolphin X Malware Adds AI Profiler to Rank and Prioritize High-Value Victims After Infection
Dolphin X is a newly identified Windows infostealer and remote access trojan that integrates an AI Profiler component designed to score infected machines and generate priority rankings for operators. The profiler analyzes telemetry from compromised systems, including application usage, browser domains visited, and installed software, to produce daily summaries that help attackers focus resources on the most valuable targets such as those with cloud access or sensitive tools. Dolphin X claims compatibility with over 300 applications, explicitly covering nine Chromium and Gecko browser families, more than 100 cryptocurrency wallet extensions, 65 desktop wallets, 10 password managers, and over 30 common cloud CLI tools. The malware targets files like .env configurations, SSH keys, cloud access tokens, browser sessions, and cryptocurrency wallet data to accelerate movement from initial credential theft to further compromises in accounts and production environments. Researchers have confirmed the AI Profiler workflow and associated scoring functions in the operator panel, although the underlying AI model itself remains unverified without full analysis of an active sample. The discovery highlights how automated prioritization can significantly shorten the time between mass infections and targeted follow-on attacks, prompting recommendations for reduced local credential storage and enhanced behavioral detection.
CVE-2026-8933: snap-confine Flaw Allows Local Root Escalation on Default Ubuntu Desktop Installs
A high-severity vulnerability tracked as CVE-2026-8933 affects snap-confine within snapd and enables unprivileged local users to obtain root access on default installations of Ubuntu Desktop 24.04, 25.10, and 26.04. The flaw stems from a hardening change that replaced traditional setuid root with Linux capabilities, inadvertently creating a race condition during sandbox initialization involving temporary files in /tmp, FUSE mounts, and symbolic links. Attackers can chain the issue with malicious udev rules to bypass AppArmor confinement and force systemd-udevd to execute commands as root. Canonical has released patched versions of snapd including 2.76.1 upstream and corresponding Ubuntu packages for multiple releases, along with ESM updates for older systems. The CVSS score of 7.8 reflects high impact on confidentiality, integrity, and availability once local access is obtained. Organizations are advised to deploy the updates immediately on workstations and developer machines while strengthening local execution controls and AppArmor policies.
Critical wp2shell Vulnerability Chain Exploited in WordPress for Unauthenticated Remote Code Execution and Webshell Deployment
A critical vulnerability chain dubbed wp2shell is being actively exploited against WordPress Core installations, enabling unauthenticated remote code execution and the installation of persistent webshells. The flaws affect versions 7.0.x prior to 7.0.2, 6.9.x prior to 6.9.5, and the 6.8 branch before 6.8.6, with patches now available. Attackers chain CVE-2026-63030 and CVE-2026-60137 through the WordPress REST API batch processing endpoint and an SQL injection in WP_Query via the author__not_in parameter. Observed campaigns involve mass scanning, user enumeration, attempts to read wp-config.php, and deployment of PHP webshells in wp-content/cache that return fake 404 responses. Administrators are urged to update immediately, audit logs for anomalous REST API requests, inspect for unauthorized admin accounts or plugins, and rotate credentials if wp-config.php exposure is suspected.
FakeGit Campaign Floods GitHub with 7,600 Fake Repositories to Distribute SmartLoader Malware
The FakeGit operation has created or repurposed approximately 7,600 repositories on GitHub to trick users and automated agents into downloading SmartLoader, a loader that installs additional malware including the StealC infostealer. Attackers clone legitimate projects, replicate documentation and developer profiles, and host malicious ZIP files in GitHub Releases that have already accumulated over 14 million downloads across roughly 200 repositories. A notable tactic called AgentBaiting targets AI systems by disguising more than 800 repositories as AI Skills or MCP servers, leading tools from Anthropic, Google, and OpenAI to recommend malicious packages. The infection chain uses LuaJIT to execute obfuscated Lua scripts that deploy SmartLoader, which establishes persistence via scheduled tasks and resolves command-and-control infrastructure through a blockchain dead drop on Polygon. Over 600 listings linked to the campaign have also appeared on public directories such as LobeHub, Glama, and MCP Market, extending the reach beyond GitHub. Defenders are advised to maintain approved catalogs of AI components, apply application control policies, and monitor for LuaJIT execution and anomalous outbound traffic.
Hugging Face Confirms Production Infrastructure Breach by Autonomous AI Agent via Malicious Dataset
Hugging Face has disclosed a sophisticated intrusion into its production environment that began with a malicious dataset and was executed by an autonomous AI agent. The attacker gained code execution in the dataset processing pipeline through a remote code execution loader and template injection, then escalated privileges and moved laterally across internal clusters over a weekend. Limited internal datasets and service credentials were accessed, but the company found no evidence of tampering with public models, Spaces, container images, or published packages. Forensic analysis processed over 17,000 attacker events using LLM-based agents, and the investigation ultimately relied on an open-weight model after commercial LLMs refused to handle real attack artifacts. Hugging Face responded by closing the initial execution paths, rebuilding compromised nodes, rotating all credentials and tokens, and tightening cluster admission controls. Users are strongly advised to immediately rotate Hugging Face access tokens, audit secrets in CI/CD pipelines and repositories, and apply least-privilege principles.
Eleven Old Microsoft-Signed UEFI Shims Enable Bypass of Secure Boot on Linux Systems Still Trusting Microsoft Corporation UEFI CA 2011
Eleven legacy UEFI shim bootloaders signed by Microsoft, all version 0.9 or earlier, can be abused to bypass UEFI Secure Boot on systems whose firmware still trusts the Microsoft Corporation UEFI CA 2011 certificate. Attackers who manage to place one of these vulnerable shims in the boot path can execute arbitrary code before the operating system loads, enabling bootkits, persistence, and kernel-level compromise with minimal visibility to traditional EDR tools. The issue stems not from a new kernel bug but from the continued validity of old, correctly signed binaries that have not yet been revoked in the DBX database. Microsoft has already issued DBX revocation updates, yet administrators must first upgrade shim, GRUB, and other boot components to modern versions that support SBAT before applying the revocations to avoid bricking systems. Affected implementations include Red Hat Enterprise Linux 7.2, CentOS 7.2, Oracle Linux 7.2, openSUSE, baramundi Management Suite up to 2024R1, WipeDrive 8.0.0–8.1.3, PC Doctor Service Center, and Abitti 1. The problem is tracked under CVE-2026-8863 and CVE-2026-10797, with public references available from The Hacker News, CERT/CC VU#616257, NIST NVD, and Help Net Security.
SonicWall Issues Emergency Hotfixes After Detecting Active Exploitation of Two Zero-Day Vulnerabilities in SMA1000 Appliances
SonicWall has confirmed active exploitation of two zero-day vulnerabilities in its SMA1000 series appliances, prompting the immediate release of hotfixes and a strict compliance deadline for U.S. federal agencies. The first flaw, CVE-2026-15409, carries a critical CVSS score of 10.0 and allows unauthenticated server-side request forgery (SSRF) through the Appliance Work Place interface, enabling attackers to force the device to make unauthorized requests to internal services. The second vulnerability, CVE-2026-15410, rated CVSS 7.2, permits authenticated code injection via the Appliance Management Console, allowing administrators to execute operating system commands. Affected models include SMA6210, SMA7210, and SMA8200v running specific vulnerable platform versions such as 12.4.3-03245 through 12.5.0-02800. CISA has added both CVEs to its Known Exploited Vulnerabilities catalog, requiring federal agencies to patch or decommission impacted systems by July 17, 2026. Indicators of compromise and recommended response actions, including log analysis and potential appliance reimaging, have been published to help organizations detect and mitigate potential intrusions.
