CVE-2026-11128: Insufficient validation of untrusted input in Google Chrome
CVE-2026-11128 is a vulnerability in Google Chrome prior to version 149. 0. 7827. 53 involving insufficient validation of untrusted input in the Web Share feature. This flaw allows a remote attacker to potentially leak cross-origin data if a user performs specific UI gestures on a crafted HTML page. The issue has been publicly disclosed but lacks a CVSS score and confirmed exploitation in the wild. The vendor advisory linked does not explicitly confirm patch availability or remediation status.
AI Analysis
Technical Summary
This vulnerability arises from improper input validation in the Web Share implementation of Google Chrome versions before 149.0.7827.53. An attacker who convinces a user to perform certain UI gestures on a maliciously crafted page can cause cross-origin data leakage. The Chromium security team rates this issue as Medium severity. No CVSS score or detailed technical exploit information is provided. The vendor advisory linked corresponds to a stable channel update announcement but does not explicitly state a fix for this vulnerability.
Potential Impact
The impact involves potential leakage of cross-origin data, which could expose sensitive information from other origins accessible in the browser context. There is no evidence of active exploitation in the wild. The severity is considered medium by the Chromium security team, indicating a moderate risk to user data confidentiality under specific user interaction conditions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. The linked Google Chrome stable channel update announcement should be monitored for updates indicating a fix. Users are advised to update to the latest Chrome version once a patch addressing this vulnerability is released. Until then, caution with untrusted web content and UI gestures involving Web Share is prudent.
