Technical details
The vulnerability exists in the POST /register and /register/complete endpoints, where the uid (user ID) parameter is not properly validated during account creation. An attacker can supply an arbitrary uid to target an existing account, then submit an empty email at the completion step to clear the victim's email and session tokens. This is an authorization bypass requiring no authentication but affecting authenticated users' account integrity.
