The vulnerability is classified as CWE\u2011843, indicating improper type handling that leads to unintended type conversion. The potential impact is the execution of code confined to the sandboxed environment of the browser, which can be a foothold for further attacks but does not directly grant native privileges.", "risk_and_exploitability": "The attack vector is remote and only requires the victim to load a malicious HTML page, making it easily reachable from any network. EPSS information is not available, and the vulnerability is not listed in the CISA KEV catalog, indicating no current widespread exploitation. The flaw bypasses the sandbox to execute code inside the browser process; while it does not explicitly claim elevation to native privileges, the ability to run arbitrary code within the sandbox can facilitate privilege escalation within the browser or enable lateral movement to other processes."}}}}, "created": "2026-04-29T02:00:26.282394+00:00", "title": "Type Confusion in V8 Enables Remote Code Execution inside Chrome Sandbox", "updated": "2026-04-29T02:45:35.946733+00:00", "vendors": ["google", "google$PRODUCT$chrome"]}
