Unauthorized invitation use via missing expiry check
Published Nov 19, 2025 · Updated Nov 20, 2025
Insufficient invitation expiration in Authentik Security Inc. authentik before 2025.8.5 or 2025.10.2 allows remote attackers to use expired invitations. The invitation stage's get_invite method queried the token with Invitation.objects.filter(...).first() without excluding records whose expires value had passed. Possession of an expired invitation token therefore preserves invitation-flow access until scheduled cleanup runs, normally within five minutes but potentially later under task backlog.
