AI Analysis
Technical Summary
CVE-2026-13803 is a type confusion vulnerability affecting Chrome Tabs in Google Chrome versions before 150.0.7871.47. An attacker who has already compromised the renderer process may exploit this flaw to perform a sandbox escape via a specially crafted HTML page. This vulnerability was assigned a high severity rating by Chromium security with a CVSS v3.1 score of 8.3, indicating significant impact on confidentiality, integrity, and availability. The vulnerability was publicly disclosed and patched in version 150.0.7871.47.
Potential Impact
Successful exploitation could allow an attacker with control over the renderer process to escape the sandbox environment, potentially leading to execution of arbitrary code with higher privileges. This compromises the security boundaries intended to isolate web content and increases the risk of system compromise.
Mitigation Recommendations
Users and administrators should update Google Chrome to version 150.0.7871.47 or later, where this vulnerability has been fixed. The vendor advisory linked confirms the availability of this update. No additional mitigations are specified beyond applying the official update.
