Kanboard through 1.2.52, fixed in commit 928c68a, UserViewController::removeSession fails to validate the session id parameter before passing it to RememberMeSessionModel::remove, allowing authenticated users to delete other users' Remember Me sessions. Attackers can enumerate sequential session IDs and mass-invalidate persistent login sessions of any user, including administrators, forcing re-authentication and causing denial of service.
