Description
ABP Framework before 10.7.1 contains an authentication bypass vulnerability that skips account state and two-factor checks when password login succeeds through a registered IExternalLoginProvider. Attackers holding the external directory password for deactivated, locked, or 2FA-protected accounts can obtain valid access tokens from the /connect/token password grant.
