CVE-2026-14409Network attack vector

Sandboxed arbitrary code execution via undisclosed V8 flaw

Published Jul 1, 2026 · Updated Jul 1, 2026

An implementation error in Google Chrome's V8 before 150.0.7871.46 allows remote attackers to execute arbitrary code inside the browser sandbox. Google identifies the affected locus only as V8 and keeps the underlying issue restricted, so the incorrect operation on untrusted input is not publicly disclosed. Execution requires a crafted HTML page and a user who performs specific UI gestures; the published impact remains confined to the sandbox, with no reported sandbox escape.
