CVE-2026-4592Public exploitNetwork attack vector

Unauthenticated password-login bypass

Published Mar 23, 2026 · Updated Mar 23, 2026

Improper authentication in KodCloud KodBox 1.64 allows remote attackers to bypass password-login controls via unspecified input. The disclosure identifies loginAfter and tfaVerify in plugins/client/controller/tfa/index.class.php, but does not reveal the manipulated input or the authentication check that fails. The path is remotely reachable without prior authentication, requires high attack complexity, and can place an attacker into an authenticated login state.
