Insufficient policy enforcement in DevTools in Google Chrome prior to 151.0.7922.72 allowed an attacker who convinced a user to install a malicious extension to leak cross-origin data via a crafted Chrome Extension. (Chromium security severity: Low)
AI Analysis
Technical Summary
CVE-2026-17927 describes a security vulnerability in Google Chrome's DevTools affecting versions before 151.0.7922.72. The vulnerability arises from insufficient policy enforcement that permits a malicious Chrome Extension, installed after user persuasion, to leak cross-origin data. This compromises the browser's same-origin policy protections via crafted extensions. The Chromium project rates this issue as low severity. There is no CVSS score provided, and no explicit patch or remediation details are included in the input data.
Potential Impact
An attacker who successfully convinces a user to install a malicious Chrome Extension can exploit this vulnerability to leak cross-origin data. This could lead to unauthorized disclosure of sensitive information accessible within the browser context. However, the impact is considered low severity by Chromium, and no active exploitation in the wild is known.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should update Google Chrome to version 151.0.7922.72 or later once available. Until then, users should exercise caution when installing Chrome Extensions, especially those from untrusted sources.
