CVE-2026-21785 MEDIUM This Month

HCL BigFix Remote Control Server WebUI versions 10.1.0.0442 and earlier expose a misconfigured Content Security Policy that omits fallback directives, permitting browsers to bypass intended origin restrictions and load unauthorized external resources. The Changed Scope (S:C) in the CVSS vector confirms that exploitation can affect resources or contexts beyond the vulnerable WebUI component itself - consistent with the XSS tag indicating potential cross-origin script injection. No public exploit code has been identified and the vulnerability is not listed in CISA KEV at time of analysis, though the high-privilege and user-interaction prerequisites substantially constrain the realistic attack surface.

CVE-2025-62316 LOW Monitor

HCL AION fails to configure security-related HTTP response headers, potentially reducing browser-based protections against cross-site scripting and other client-side attacks. The vulnerability requires adjacent network access, high interaction complexity, low privilege authentication, and user interaction to achieve limited confidentiality impact. CVSS score of 2.3 reflects minimal real-world risk under current attack conditions.

Cross-site scripting (XSS) in GitLab CE/EE 18.11 before 18.11.1 allows authenticated users to inject unauthorized content into other users' browsers through improper input validation in the Mermaid diagram sandbox. An attacker must have valid GitLab credentials and the victim must view a malicious diagram, limiting real-world impact despite the publicly available exploit code. SSVC analysis rates this as non-automatable with partial technical impact, consistent with the low CVSS 3.5 score.

CVE-2026-32187 MEDIUM PATCH This Month

Microsoft Edge (Chromium-based) contains a defense-in-depth vulnerability affecting all versions that allows remote attackers to disclose sensitive information and modify data through a network-based attack requiring user interaction. The vulnerability carries a CVSS score of 4.2 (low severity) with high attack complexity, indicating limited real-world exploitability despite dual confidentiality and integrity impacts. A vendor-released patch is available from Microsoft.

CVE-2026-2378 HIGH PATCH This Week

ArcSearch for Android versions prior to 1.12.7 contains an address bar spoofing vulnerability that allows attackers to display a different domain in the browser's address bar than the actual content being rendered. Users of ArcSearch for Android prior to version 1.12.7 are affected, and an attacker can craft malicious web content that, after user interaction, deceives users into believing they are visiting a legitimate domain while viewing attacker-controlled content. There is no indication of active exploitation in KEV data, and EPSS data is not provided.
