CVE-2026-17899

Privilege escalation via DevTools policy enforcement

Published Jul 30, 2026 · Updated Jul 30, 2026

Insufficient policy enforcement in Google Chrome before 151.0.7922.72 allows attackers to escalate privileges through a crafted extension. The public record identifies DevTools policy enforcement as the locus but does not disclose which policy check or privileged operation is mishandled. Exploitation requires a user to install a malicious Chrome extension; the resulting elevated access is not further bounded in public vendor material.
