CVE-2026-6312: Insufficient policy enforcement in Google Chrome
Insufficient policy enforcement in Passwords in Google Chrome prior to 147.0.7727.101 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
AI Analysis
Technical Summary
This vulnerability arises from insufficient policy enforcement in the Passwords feature of Google Chrome versions before 147.0.7727.101. An attacker with control over the renderer process can exploit this weakness to leak data across origins by using a specially crafted HTML page. The issue is tracked as CWE-284 (Improper Access Control). The CVSS 3.1 vector indicates network attack vector, high attack complexity, no privileges required, user interaction required, unchanged scope, and low confidentiality impact.
Potential Impact
The impact is limited to potential leakage of cross-origin data if an attacker has already compromised the renderer process. There is no impact on integrity or availability. The confidentiality impact is low, and no known exploits have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/04/stable-channel-update-for-desktop_15.html for current remediation guidance. Until an official fix is confirmed, users should exercise caution with untrusted content and consider updating to the latest Chrome version once available.
