CVE-2026-11205: Insufficient validation of untrusted input in Google Chrome
A vulnerability in Google Chrome for iOS prior to version 149.0.7827.53 allows insufficient validation of untrusted input. This flaw enables a remote attacker to inject arbitrary scripts or HTML via a crafted QR code if the user performs specific UI gestures, resulting in a UXSS (Universal Cross-Site Scripting) condition. The vulnerability has a medium severity rating and a CVSS score of 6.1.
AI Analysis
Technical Summary
CVE-2026-11205 is a vulnerability in Google Chrome on iOS where insufficient validation of untrusted input allows a remote attacker to inject arbitrary scripts or HTML (UXSS) through a crafted QR code. Exploitation requires the user to engage in specific UI gestures. The issue affects Chrome versions prior to 149.0.7827.53. The vulnerability is classified under CWE-20 (Improper Input Validation) and has a medium severity with a CVSS 3.1 score of 6.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N). No known exploits are reported in the wild. The vendor advisory linked does not explicitly confirm patch availability or remediation status.
Potential Impact
Successful exploitation can lead to partial compromise of confidentiality and integrity by allowing arbitrary script or HTML injection via UXSS. This could enable attackers to execute malicious scripts in the context of the browser, potentially leading to data theft or manipulation. Availability is not impacted. The attack requires user interaction (UI gestures) and remote network access.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should update Google Chrome on iOS to version 149.0.7827.53 or later once the update is officially released and confirmed. Until then, avoid scanning untrusted QR codes and be cautious with UI gestures prompted by unknown sources. Monitor the official Google Chrome release blog for updates.
