Parse Server before 8.6.102 and 9.0.0 before 9.10.5-alpha.2 contains an authentication bypass because the validateSetUp, validateLogin, and validateUpdate methods of custom adapters subclassing AuthAdapter are never called, and an inherited default that accepts any authData is used instead. Attackers can supply arbitrary authData to sign up, link identities, log in as existing users, or skip custom additional authentication factors.
