GHSA-m492-gv72-xvxj: Kimai Password Reset Link Remains Valid After Password Change

The LoginLink signature used for password reset URLs covers only the user’s id — it does not include the password hash. After a user clicks a reset link and successfully changes their password, the same link remains valid for up to 2 additional uses within a 1-hour window. Anyone who intercepts or caches the original link can log in as the user even after the password has been changed.
