Summary
blueprintUE self-hosted edition before 4.3.4 contains an insufficient session expiration vulnerability that allows attackers to confirm accounts using stale tokens because UserModel::findUserIDWithConfirmedToken ignores confirmed_sent_at. Attackers who obtain an old confirmation link from a compromised mailbox, backup, or forwarded mail can activate unconfirmed accounts and evade the unconfirmed-account cleanup job.
