CVE-2026-19164: Insufficient validation of untrusted input in Google Chrome
Insufficient validation of untrusted input in Codecs in Google Chrome prior to 151.0.7922.109 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
AI Analysis
Technical Summary
CVE-2026-19164 describes an insufficient input validation vulnerability in the Codecs component of Google Chrome versions before 151.0.7922.109. This weakness enables a remote attacker to potentially escape the browser's sandbox environment through a specially crafted HTML page, which could lead to execution of code outside the intended security boundaries. The vulnerability is categorized under CWE-20 (Improper Input Validation).
Potential Impact
Successful exploitation could allow an attacker to bypass Chrome's sandbox protections, potentially leading to execution of arbitrary code with elevated privileges outside the browser sandbox. This increases the risk of system compromise or further attacks originating from the browser context.
Mitigation Recommendations
A fix is available in Google Chrome version 151.0.7922.109. Users and administrators should update to this version or later to remediate the vulnerability. Since this is a client software vulnerability, patching the affected browser versions is the recommended mitigation.
