NVIDIA Patches Critical VIRTIO-Net Flaw in BlueField 3 Allowing VM Code Execution
NVIDIA has issued a security update to address a critical vulnerability in the VIRTIO-Net component of its BlueField 3 DPU platform.
The flaw, identified as CVE-2026-65094, was disclosed in a security advisory published on July 28, 2026. It stems from improper handling of memory write operations and was discovered internally by the company. The original CVE identifier CVE-2025-33209 was withdrawn and replaced.
According to the advisory, a virtual machine user can exploit the vulnerability by sending specially crafted messages. This allows arbitrary values to be written to arbitrary memory locations, enabling code execution within the VIRTIO-Net execution context.
The vulnerability received a CVSS v3.1 base score of 9.0 and is rated Critical, the highest severity level.
NVIDIA recommends updating to the following fixed versions or later: VIRTIO-Net 25.10.6, 25.10.2, 24.10.50, and 23.10.23.

Adobe Patches Critical Vulnerabilities in Bridge and Format Plugins
Adobe has released security updates addressing multiple critical vulnerabilities in Adobe Bridge and Adobe Format Plugins. The updates, published on July 28, 2026, resolve eight flaws in Adobe Bridge including search path issues tracked as CVE-2026-48395 and CVE-2026-48391, authorization problems under CVE-2026-48396 and CVE-2026-48390, plus path traversal CVE-2026-48374 and out-of-bounds write vulnerabilities CVE-2026-48392, CVE-2026-48393, and CVE-2026-48394. Adobe Format Plugins received a fix for the heap-based buffer overflow CVE-2026-48372 that could allow arbitrary code execution. The company published separate security advisories detailing the affected versions and remediation steps. These patches close attack vectors that could lead to remote code execution or unauthorized access when users open malicious files or rely on untrusted paths.
SOC Incident Analysis Exposes Active Exploitation of CVE-2025-53770 SharePoint ToolShell Auth Bypass and RCE
A detailed walkthrough of Letsdefend SOC342 demonstrates how analysts detected and confirmed exploitation of CVE-2025-53770 targeting SharePoint servers. The alert was triggered by a suspicious unauthenticated POST request to ToolPane.aspx carrying an unusually large payload and a spoofed referer. Investigation revealed that the vulnerable server accepted the request, after which PowerShell commands extracted ASP.NET cryptographic keys, enabling ViewState forgery and remote code execution. Attackers then compiled and dropped additional payloads using csc.exe and created a malicious spinstall0.aspx page that leveraged WScript.Shell to download further malware. Network indicators included the malicious IP 107.191.58.76 flagged by CISA and multiple VirusTotal detections. The server was isolated, files removed, and cryptographic keys rotated to contain the breach.
GitLab Developer Account Leads to Full OpenStack Cloud Control via CI/CD Runner Misconfigurations
A penetration testing team demonstrated how a standard developer account in GitLab can be escalated to full administrative control over an OpenStack cloud environment through typical CI/CD misconfigurations. Starting with only GitLab credentials, the testers created a pipeline that executed arbitrary commands on a production Kubernetes runner named PROD-K8S-RUNNER01. Membership in the docker group allowed privilege escalation to root by mounting the host filesystem and adding an SSH key. From the compromised host, the team discovered a kubeconfig file granting extensive Kubernetes permissions including secret access, pod execution, and role bindings. This access enabled mounting a node filesystem to extract OpenStack cloud-config credentials. The resulting cloud account possessed broad roles across nova, cinder, neutron, and other services, effectively providing administrator-level control over virtual machines, networks, storage, and managed Kubernetes clusters.
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.
