Just-In-Time compilation is the performance heart of every modern browser JavaScript engine. It is also one of the most complex and historically exploitable attack surfaces in consumer software. Project Glasswing's Claude Mythos identified a JIT vulnerability through coordinated disclosure with browser vendors. This is a technical deep-dive for security engineers who need to understand the attack surface and harden their enterprise browser deployments.
Project Glasswing's Claude Mythos AI achieved 21 out of 41 arbitrary code execution exploits in the V8 JavaScript engine on Anthropic's ExploitBench evaluation. No other AI model scored above zero. V8 ACE is among the 9 confirmed Glasswing CVEs, meaning a drive-by browser compromise via a malicious webpage is within scope. This post explains the vulnerability class, the benchmark results, and what enterprise Chrome management teams should do now.
Chrome V8 zero-day CVE-2026-11645 confirmed active exploitation — CVSS 8.8, CISA KEV listed, 3.5B Chrome users exposed. Patch to 149.0.7827.103 now.
