CVE-2023-4762Known exploitationNetwork attack vector

Code execution via undisclosed V8 type confusion

Published Sep 5, 2023 · Updated Oct 21, 2025

Type confusion in V8 in Google Chrome before 116.0.5845.179 allows remote attackers to execute arbitrary code via a crafted HTML page. Google disclosed the affected V8 component but restricted the underlying issue report, so the confused object types and incorrect operation on attacker-controlled data are not public. Execution requires a user to open the crafted page; reported exploitation is active, and resulting code runs within Chrome's security context.
