There is no CVSS score provided, and no explicit patch or remediation level is confirmed in the vendor advisory. No known exploits are reported in the wild.
AI Analysis
Technical Summary
This vulnerability affects Google Chrome on iOS before version 149.0.7827.53. It arises from insufficient validation of untrusted input when processing QR codes combined with specific user interface gestures. An attacker who convinces a user to perform these gestures with a crafted QR code can inject arbitrary scripts or HTML, leading to a UXSS condition. The issue is documented with medium severity by Chromium security. The vendor advisory linked does not explicitly confirm patch availability or remediation status.
Potential Impact
Successful exploitation could allow an attacker to execute arbitrary scripts or inject HTML content within the context of the affected Chrome browser on iOS. This could lead to unauthorized actions or data exposure within the browser session. However, no known exploits in the wild have been reported, and the severity is rated medium by Chromium security.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html for current remediation guidance. Users should update to Chrome version 149.0.7827.53 or later once confirmed. Until then, avoid scanning untrusted QR codes or performing unexpected UI gestures in Chrome on iOS.
