CVE-2026-6313: Insufficient policy enforcement in Google Chrome
Insufficient policy enforcement in CORS 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 in Google Chrome relates to insufficient policy enforcement in Cross-Origin Resource Sharing (CORS). Specifically, it allows a remote attacker with control over the renderer process to bypass CORS restrictions and leak data from other origins by using a specially crafted HTML page. The affected versions are prior to 147.0.7727.101. The CVSS score of 3.1 reflects a low severity impact, with network attack vector, high attack complexity, no privileges required, and user interaction needed. The vulnerability is categorized under CWE-284 (Improper Access Control).
Potential Impact
The impact is limited to information disclosure of cross-origin data if an attacker has already compromised the renderer process. There is no indication of integrity or availability impact. The low CVSS score and absence of known exploits suggest limited practical risk under normal conditions.
Mitigation Recommendations
Patch status is not yet confirmed from the provided data. The vendor advisory link should be consulted for the latest remediation guidance. Until confirmed, users should update to the latest Chrome version once available. No additional mitigation steps are specified in the advisory.
