Description
Plane is an open-source project management tool. Prior to 1.4.0, a user whose account has been deactivated by setting is_active=False can still log in with existing credentials. Successful authentication silently changes is_active back to True, reactivating the account without notifying the administrator. This issue is fixed in 1.4.0.
