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.

Fuzzy Logic in Cybersecurity: Reducing Vulnerability Queue by 7.5 Times with CVSS, EPSS and FSTEC Comparison
An information security specialist has developed a fuzzy logic system that prioritizes vulnerabilities far more effectively than traditional scoring methods. The approach uses linguistic variables and membership functions to handle the inherent uncertainty in exploitability and impact assessments. By integrating EPSS probability data with CVSS impact scores and vulnerability age, the model reduces the actionable backlog by a factor of 7.5. The implementation relies on the Mamdani inference algorithm and trapezoidal membership functions to produce smooth, human-interpretable urgency ratings. Detailed coverage checks and rule-base validation ensure no gaps exist in the decision space. Real-world testing on CVE-2025-49113 in Roundcube Webmail demonstrated practical advantages over rigid threshold logic. The method is positioned as a practical enhancement rather than a replacement for existing standards.
VLC Media Player Hit by Two Memory Corruption Flaws Exploitable via Malicious PNG and Rogue RealRTSP Server
Two vulnerabilities have been discovered in the VLC media player that allow out-of-bounds memory access. The issues affect versions from 3.0.0 through 3.0.23. CVE-2026-56711, rated 8.6 on CVSS 4.0, stems from an integer overflow when calculating image buffer sizes in PNG files, enabling attackers to trigger writes beyond allocated memory simply by opening a crafted image or loading it from a playlist. CVE-2026-73324, scored 6.9, resides in the RealRTSP module and permits a malicious server to send an oversized response string that causes reads past the end of a buffer due to a missing null terminator. Both flaws are present in official VideoLAN builds, although some distributions may exclude the RealRTSP component. No special configuration or plugins are required to trigger the issues. Until patched releases appear, users are advised to avoid opening images or playlists from untrusted sources and to refrain from connecting to unknown RealRTSP streams.
September Windows 11 Security Update KB5124008 Breaks Always On VPN Certificate Authentication
The September security update KB5124008 for Windows 11 has introduced a regression that disables Always On VPN connections using certificate-based authentication. The issue affects devices running Windows 11 versions 24H2 and 25H2 that connect to Remote Routing and Access Service (RRAS) and Network Policy Server (NPS) instances on Windows Server 2019. VPN profiles deployed via Microsoft Intune are impacted, with the failure occurring during the certificate negotiation phase of the IPsec connection. Users confirm the problem is reproducible: the VPN works before the patch, stops after installation, and resumes after patch removal and reboot. Microsoft has not yet acknowledged the regression or released a fix, leaving administrators to pause deployment through WSUS or Intune and open support cases with client and NPS logs. A potential workaround involves switching profiles to EAP-TLS, though its reliability remains unconfirmed.
API Token Lifecycle: From Issuance to Revocation and Secure Management
The article provides a comprehensive examination of the full API token lifecycle in browser-based applications, emphasizing that signatures alone cannot prevent token theft. It details risks introduced at issuance, storage, transmission, and revocation stages, including improper OAuth grant types and long-lived tokens. Key recommendations include short-lived access tokens, atomic refresh token rotation, and the use of Authorization Code Flow with PKCE for public clients. Storage advice strongly discourages localStorage and sessionStorage in favor of HttpOnly cookies or a Backend-for-Frontend pattern that keeps real tokens on the server. The piece also covers CSRF protections, rate limiting on authorization endpoints, and the advantages of signed client assertions over static secrets. Overall, it stresses that token security depends on the entire lifecycle architecture rather than cryptographic strength alone.
