AI Analysis
Technical Summary
This vulnerability (CVE-2026-11287) affects Google Chrome on Android versions before 149.0.7827.53. It stems from insufficient validation of untrusted input related to navigation policy enforcement. An attacker with control over the renderer process can bypass navigation restrictions by leveraging a specially crafted HTML page. The issue is categorized under CWE-602 (Improper Restriction of XML External Entity Reference). The CVSS 3.1 vector indicates the attack requires network access, low attack complexity, no privileges, user interaction, and impacts integrity without affecting confidentiality or availability.
Potential Impact
An attacker who has already compromised the renderer process can bypass navigation restrictions, potentially leading to unauthorized actions or manipulation of navigation flows within the browser. This could affect the integrity of the browsing session but does not impact confidentiality or availability. No known exploits in the wild have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. The provided vendor advisory link does not explicitly state a fix or mitigation. Users and administrators should monitor official Google Chrome release notes and update to version 149.0.7827.53 or later once a fix is confirmed.
