CVE-2026-17988 is a vulnerability in Google Chrome prior to version 151.0.7922.72 involving insufficient validation of untrusted input in the navigation component. This flaw allows a remote attacker who has already compromised the renderer process to bypass navigation restrictions by using a crafted HTML page. The vulnerability is rated with low severity by Chromium security. No CVSS score is provided. There is no explicit vendor advisory stating a patch or fix, but the affected version is identified as exactly 151.0.7922.72, implying that this version addresses the issue.
AI Analysis
Technical Summary
This vulnerability in Google Chrome's navigation handling arises from insufficient validation of untrusted input. An attacker with control over the renderer process can exploit this to bypass navigation restrictions via a crafted HTML page. The issue affects Chrome versions prior to 151.0.7922.72. The Chromium security team classifies this vulnerability as low severity. No detailed CVSS score or explicit remediation level is provided in the available data. The vendor advisory link points to a stable channel update announcement, suggesting that version 151.0.7922.72 includes the fix.
Potential Impact
The impact is limited to bypassing navigation restrictions by an attacker who has already compromised the renderer process. This means the attacker must have some level of code execution or control within the renderer context before exploiting this vulnerability. The Chromium security severity is low, indicating limited risk or impact from this issue alone. There are no known exploits in the wild.
Mitigation Recommendations
The vulnerability is addressed in Google Chrome version 151.0.7922.72. Users and administrators should update to this version or later to remediate the issue. Since this is a client-side application, applying the official stable channel update from Google is the recommended remediation. No additional mitigation steps are indicated by the vendor advisory.
