CVE-2026-17837: Insufficient validation of untrusted input in Google Chrome
Insufficient validation of untrusted input in DevTools 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: Medium)
AI Analysis
Technical Summary
This vulnerability involves insufficient validation of untrusted input within the DevTools component of Google Chrome versions before 151.0.7922.72. An attacker with control over the renderer process could exploit this flaw to perform a sandbox escape, which could lead to executing code outside the browser's restricted environment. The CVSS 3.1 score of 9.6 reflects network attack vector, low attack complexity, no privileges required, user interaction required, scope change, and high impact on confidentiality, integrity, and availability. The vulnerability is publicly disclosed with a vendor advisory link but lacks explicit patch or remediation details in the provided data.
Potential Impact
Successful exploitation can allow an attacker who has compromised the renderer process to escape the Chrome sandbox, potentially leading to execution of arbitrary code with higher privileges than normally permitted. This could compromise system security and user data confidentiality, integrity, and availability. The vulnerability is rated critical due to the potential for full system compromise following sandbox escape.
Mitigation Recommendations
The vendor advisory linked indicates a stable channel update for Chrome but does not explicitly confirm patch availability or remediation level. Given the vulnerability affects versions prior to 151.0.7922.72, updating to version 151.0.7922.72 or later is strongly recommended. Patch status is not yet confirmed explicitly; users should consult the vendor advisory for the latest remediation guidance.
