CVE-2026-109379

Cockpit CMS 2.14.1 contains an observable timing discrepancy vulnerability that allows unauthenticated attackers to enumerate accounts due to an incomplete timing fix in /auth/check. Attackers can post login attempts and measure response times, since existing accounts incur two bcrypt operations versus one, revealing valid usernames and email addresses.
