CVE-2026-93373 [CRITICAL] CWE-825 chromium-browser: chromium-browser: Arbitrary code execution outside the sandbox via crafted extension
chromium-browser: chromium-browser: Arbitrary code execution outside the sandbox via crafted extension
Use after free in Extensions in Google Chrome prior to 153.0.8010.52 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted Chrome extension. (Chromium security severity: High)
A flaw was found in the Extensions component of Chromium. This vulnerability is caused by a use-after-free condition, where the application attempts to access system memory after it has already been released. A remote attacker could exploit this flaw by enticing a user to install or run a specially crafted browser extension. Successful exploitation allows the attacker to bypass browser security boundaries (sandbox) and execute arbitrary code on the target system.
