Use after free in FedCM in Google Chrome prior to 146.0.7680.165 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Remote code execution in Google Chrome's Federated Credential Management (FedCM) prior to version 146.0.7680.165 enables unauthenticated attackers to execute arbitrary code within the browser sandbox through a malicious HTML page. This use-after-free vulnerability in memory management affects Chrome on all supported platforms and requires only user interaction to trigger. A patch is available in Chrome 146.0.7680.165 and later.
Technical ContextAI
The vulnerability resides in FedCM (Federated Credential Management), a web standard that facilitates identity federation by allowing users to sign in with third-party identity providers without sharing personal information with the website. The root cause is classified as CWE-416 (Use After Free), a memory safety issue where freed memory is accessed after deallocation, leading to unpredictable behavior and potential code execution. The affected product is Google Chrome (cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*), a widely deployed browser engine. The use-after-free condition likely occurs in FedCM's internal state management during credential exchange workflows, allowing an attacker to corrupt memory and gain control of execution flow within the sandboxed browser process.
RemediationAI
Upgrade Google Chrome to version 146.0.7680.165 or later immediately. Users can trigger an automatic update by restarting the browser or manually check for updates via Chrome Settings > About Google Chrome, which will auto-update to the latest stable release. For organizations managing Chrome deployments, configure automatic updates via group policy (Windows) or equivalent mobile device management (MDM) solutions for all platforms. In the interim, if immediate patching is not feasible, consider restricting Chrome usage to trusted internal websites only and disable FedCM functionality via enterprise policies (chrome.admx for Windows domains) until patches can be applied. Monitor the Chromium issue tracker (issues.chromium.org/issues/491869946) and Chrome Releases blog for any follow-up security advisories.
