CVE-2026-82449Network attack vectorHinoki check available

Unauthenticated account enumeration via password-check timing

Published Aug 29, 2026 · Updated Aug 29, 2026

Observable timing discrepancy in Cockpit CMS before 2.14.1 allows remote attackers to enumerate accounts through the auth check endpoint. The Auth controller calls password_verify only when a submitted account exists, while unknown accounts return immediately without equivalent bcrypt work. No authentication or user interaction is required, but reliable enumeration depends on comparing response times across multiple requests.
