Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-287.

Summary

Parse Server before 8.6.102 and from 9.0.0 before 9.10.5-alpha.2 contains an authentication bypass (CWE-287) because the validateSetUp, validateLogin, and validateUpdate methods of custom adapters that subclass AuthAdapter are never called. The inherited default accepts any authData instead. An unauthenticated remote attacker can supply arbitrary authData to sign up, link identities, log in as existing users, or skip custom additional authentication factors.

Attackers can supply arbitrary authData to sign up, link identities, log in as existing users, or skip custom additional authentication factors.
