Kimai before 2.58.0 Authentication Bypass via Password Reset Link

Published Aug 25, 2026 · Updated Oct 8, 2026 · Assigned by VulnCheck

Description

Kimai before 2.58.0 contains an authentication bypass vulnerability where password reset links remain valid after password changes because the LoginLink signature covers only the user id, not the password hash. Attackers who intercept or cache a password reset link can use it up to 2 additional times within a 1-hour window to log in as the user even after the legitimate user has changed their password.
