Insufficient validation of untrusted input in AI in Google Chrome prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Low)
AI Analysis
Technical Summary
CVE-2026-17991 is a vulnerability in Google Chrome's AI component where insufficient validation of untrusted input allows a remote attacker with control over the renderer process to potentially perform a sandbox escape. This could be triggered via a specially crafted HTML page. The vulnerability affects versions of Google Chrome prior to 151.0.7922.72. No CVSS score is available, but the Chromium security severity is classified as low. There are no known exploits in the wild and no patch links were provided in the data.
Potential Impact
If exploited, an attacker who has already compromised the renderer process could escape the sandbox, potentially increasing their privileges or access on the affected system. However, the overall severity is considered low by the Chromium security team, indicating limited impact or difficulty in exploitation.
Mitigation Recommendations
A fix is available in Google Chrome version 151.0.7922.72 and later. Users and administrators should update to this version or later to remediate the vulnerability. Since this is a client software vulnerability, patching the browser is the recommended mitigation. No other specific mitigations are indicated.
