🚨 CRITICAL - Chrome DevTools policy enforcement flaw enables sandbox escape (CVE-2026-13909) CVE-2026-13909 is an insufficient policy enforcement issue in Google Chrome’s DevTools component (Chromium) affecting versions prior to 150.0.7871.47. The root cause is improper enforcement of security policy boundaries, allowing restricted actions to be performed when they should be blocked. An attacker can exploit this by luring a target to a crafted HTML page and, after achieving a renderer-process compromise, chaining the weakness to escape the sandbox. If exploited, this can turn a renderer-level foothold into broader system compromise, enabling sandbox escape and follow-on code execution or data access outside the renderer constraints. 👉 Affected: Google Chrome < 150.0.7871.47 | Upgrade to 150.0.7871.47 or later
Post summary
Google Chrome’s DevTools policy enforcement flaw (CVE-2026-13909) permits sandbox escape via crafted HTML, and users are advised to upgrade to version 150.0.7871.47 or later for remediation.
