CVE-2026-13856: Insufficient validation of untrusted input in Google Chrome
Insufficient validation of untrusted input in Speech in Google Chrome on Android prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to perform privilege escalation via a crafted HTML page. (Chromium security severity: Medium)
AI Analysis
Technical Summary
This vulnerability arises from insufficient validation of untrusted input in the Speech feature of Google Chrome on Android. An attacker with control over the renderer process can leverage a specially crafted HTML page to escalate privileges. The issue affects Chrome versions before 150.0.7871.47. The CVSS vector indicates network attack vector, high complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows a remote attacker, who has already compromised the renderer process, to escalate privileges within the affected Chrome environment on Android. This can lead to full compromise of the browser process, potentially impacting confidentiality, integrity, and availability of user data and browser functionality.
Mitigation Recommendations
The vulnerability is addressed in Google Chrome version 150.0.7871.47. Users and administrators should update to this version or later to remediate the issue. The vendor advisory linked should be consulted for official update instructions. No additional mitigation steps are indicated.
