CVE-2026-17927 is a vulnerability in Google Chrome prior to version 151.0.7922.72 involving insufficient policy enforcement in DevTools. This flaw allows an attacker who convinces a user to install a malicious extension to leak cross-origin data via a crafted Chrome Extension. The vulnerability is rated as low severity by Chromium security. No CVSS score is provided.
AI Analysis
Technical Summary
This vulnerability arises from insufficient policy enforcement in the DevTools component of Google Chrome versions before 151.0.7922.72. An attacker leveraging this issue can convince a user to install a malicious Chrome extension that exploits this weakness to leak data across origins, violating the same-origin policy. The issue is specific to Chrome desktop and does not have known exploits in the wild. The vendor advisory linked does not explicitly state patch availability or remediation level.
Potential Impact
An attacker who successfully convinces a user to install a malicious extension can leak cross-origin data, potentially exposing sensitive information from other web origins. The impact is limited by the requirement for user interaction (installing the malicious extension) and is rated low severity by the Chromium security team.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html for current remediation guidance. Users and administrators should ensure Chrome is updated to the latest stable version beyond 151.0.7922.72 when available. Avoid installing untrusted extensions to reduce risk.
