CVE-2026-15122: Insufficient validation of untrusted input in Google Chrome
Insufficient validation of untrusted input in Codecs in Google Chrome on Windows prior to 150.0.7871.115 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
AI Analysis
Technical Summary
This vulnerability arises from insufficient validation of untrusted input within the Codecs component of Google Chrome on Windows. An attacker who has compromised the renderer process could exploit this flaw to perform a sandbox escape by delivering a specially crafted HTML page. The sandbox escape could lead to increased privileges and further compromise of the host system. The vulnerability is tracked as CVE-2026-15122 with a CVSS 3.1 base score of 8.3 (High). The issue is resolved in Chrome version 150.0.7871.115.
Potential Impact
Successful exploitation allows a remote attacker, with prior access to the renderer process, to escape the sandbox environment. This could lead to full compromise of the affected system, including execution of arbitrary code with elevated privileges, resulting in confidentiality, integrity, and availability impacts rated as high.
Mitigation Recommendations
A fix is available in Google Chrome version 150.0.7871.115. Users and administrators should update affected Chrome installations to this version or later to remediate the vulnerability.
