Technical details
The NestJS auth service fails to validate that a user can only modify their own account identifier during update requests, allowing a registered user to submit a user-controlled user ID parameter that overwrites another account's identifier. This mass assignment vulnerability allows account takeover without requiring elevated privileges or special authentication beyond a valid user account.
