Critical Zero-Day CVE-2026-75650 in Adobe Commerce and Magento Allows Unauthenticated Remote Code Execution, Already Exploited

Adobe has issued an urgent security update for Adobe Commerce and Magento after identifying a severe zero-day vulnerability that allows unauthenticated remote code execution. The flaw, designated CVE-2026-75650, has already been exploited in active attacks, prompting the company to release a hotfix and assign the highest remediation priority.

The vulnerability arises because the template engine fails to properly neutralize special elements, enabling attackers to inject and execute arbitrary code remotely without requiring any credentials. Adobe published its security advisory on September 7, 2026, classifying the issue as Critical — the highest of its three-tier severity scale.

Under the CVSSv3.1 scoring system, the vulnerability received the maximum base score of 10.0, confirming its extreme risk level. Adobe states that real-world exploitation has been observed, which significantly raises the urgency for organizations running affected versions.

To address the issue, Adobe has prepared a dedicated hotfix that resolves CVE-2026-75650. The company rates the update priority as 1 on its three-tier scale and recommends applying the patch within 72 hours whenever possible.

Customers are strongly advised to review the official Adobe security advisory and deploy the fix immediately to prevent potential compromise of their e-commerce platforms.

Dissecting CVE-2026-83557 in jackson-databind: Why Not Every CVE Requires Immediate Panic

A detailed analysis of CVE-2026-83557 reveals that the vulnerability in jackson-databind affects only a narrow set of configurations involving polymorphic deserialization with the Comparable base type. The flaw stems from an incomplete denylist in DefaultBaseTypeLimitingValidator, which overlooks java.lang.Comparable when the MapperFeature.BLOCK_UNSAFE_POLYMORPHIC_BASE_TYPES flag is explicitly enabled. Researchers constructed working proof-of-concept exploits showing that an attacker can instantiate classes such as java.io.File, but only when the property is declared as Comparable<?> and the protective flag is active. The issue impacts versions 2.11 through 2.22.1, yet the CVSS score of 5.6 reflects its moderate real-world risk because most applications lack the required Comparable-typed polymorphic fields. Patching introduces its own trade-off by blocking legitimate Comparable subclasses, forcing developers to implement custom BasicPolymorphicTypeValidator allowlists. The case highlights how dependency scanners often flag CVEs without considering application-specific configuration and DTO structures.

Multiple Critical Vulnerabilities Found in Citrix NetScaler ADC and Gateway, Two Actively Exploited

Cloud Software Group disclosed eight vulnerabilities affecting NetScaler ADC and NetScaler Gateway products on September 27, 2026. Two of the issues, CVE-2026-88771 and CVE-2026-88772, have already been confirmed as exploited in the wild, prompting urgent remediation advice. CVE-2026-88771 stems from insufficient input validation and allows unauthenticated remote code execution across all default configurations. CVE-2026-88772 involves a memory overflow that can lead to code execution or denial of service when DTLS is enabled, which occurs by default on VPN vServers. The remaining six vulnerabilities cover code execution, denial of service, and HTTP request smuggling risks, with the advisory rated Critical overall. Organizations are urged to apply patches immediately and investigate potential breaches.

YApi Abandoned Since 2022: Fork Yapix Exposes Forgable Project Tokens and Critical Sandbox Flaws

YApi, a widely used open-source API documentation and mocking platform with 27.7k GitHub stars, has received no updates since its 1.12 release in November 2022. The project accumulated 1,629 open issues, including an unaddressed remote code execution report via mock scripts. Security researcher Perruer created the Yapix fork to address broken dependencies, Node.js 22 incompatibility with deprecated crypto.createCipher, and 244 known vulnerabilities in production dependencies. Analysis revealed that project tokens could be forged by any user because the default passsalt key was a hardcoded five-character string published on GitHub. The original implementation used vm2 and Node vm for script execution, both of which are unsafe, allowing arbitrary server-side code execution. Yapix migrates to isolated-vm with strict memory and time limits, replaces SHA-1 password hashing with scrypt, and blocks MongoDB operator injection in API parameters.

Researchers Bypass RP2350 Secure Debug Lock with Laser Fault Injection and Photon Emission Microscopy

Security researchers have demonstrated a hardware attack that restores Secure Debug access on the RP2350 microcontroller revision A4 despite permanent OTP fuses disabling it. Using photon emission microscopy they first located the exact physical bits of the DEBUGEN register, then applied precisely timed 980 nm laser pulses to flip two critical bits and re-enable the Mem-AP ports. The attack requires decapping the chip from the backside and laboratory equipment costing around $250,000, but succeeds in seconds once calibrated. It bypasses the CRIT1.DEBUG_DISABLE fuse, TrustZone restrictions, and glitch detectors by resetting the device before firmware can re-lock the OTP page. The technique was developed against the updated A4 silicon released after the first Raspberry Pi Hacking Challenge. The work highlights that even heavily hardened microcontrollers remain vulnerable to sophisticated physical attacks when an attacker has direct silicon access.
