CVE-2026-92578

Description

WWBN AVideo through 29.0 contains an authentication bypass vulnerability where the stored password hash is accepted as a valid login credential through two independent code paths in loginFromRequest() and encryptPasswordVerify(). Attackers who obtain the stored users.password hash value can authenticate as any user by submitting the hash directly to login endpoints, completely bypassing password verification.
