Sandboxed code execution in Dawn in Google Chrome
CVE-2026-11086 is an inappropriate implementation vulnerability in Dawn affecting Google Chrome versions prior to 149.0.7827.53. According to the provided content, the flaw allows a remote attacker, after first compromising the renderer process, to trigger arbitrary code execution inside the Chrome sandbox by using a crafted HTML page. The available material also maps the issue to CWE-20, indicating insufficient validation of untrusted input in the affected Dawn component. The vulnerable condition is therefore not a direct sandbox escape from the web alone, but a post-renderer-compromise issue reachable through malicious web content.
