Source agreement

0/2

Evidence confidence

Short explanation

ABP Framework versions prior to 10.7.1 contain an authentication bypass vulnerability that skips account state and two-factor checks when password login succeeds through a registered IExternalLoginProvider.

Why does it matter?

Attackers holding the external directory password for deactivated, locked, or 2FA-protected accounts can obtain valid access tokens from the /connect/token password grant.

What should be done?

  • Follow vendor advisories and patches
  • Review related commit and pull request references
  • Keep versions updated
