Summary
The ABP Framework before version 10.7.1 has an authentication bypass that lets a remote attacker who holds the external directory password for a deactivated, locked, or two-factor-protected account get valid access tokens without passing those account checks. The attacker needs a low-privilege login to reach the flaw, and no user action is required.
Read the original 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.

Questions about CVE-2026-123618
Is CVE-2026-123618 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
When password login succeeds through an external login provider, the usual account state and two-factor checks are skipped. The /connect/token password grant can then issue valid access tokens for deactivated, locked, or 2FA-protected accounts.Source: vulncheck.com
Which versions are affected by CVE-2026-123618?
abp: before 10.7.1.Source: cve.now feed data
Am I affected, and how do I check?
ABP Framework versions before 10.7.1 are affected, but only where a registered IExternalLoginProvider is used when password login succeeds. To check, look at the ABP Framework version in use and whether the application registers an IExternalLoginProvider.Source: vulncheck.com
How do I fix CVE-2026-123618?
Upgrade ABP Framework to 10.7.1, the listed fixed version. The facts list no workaround for versions before that.Source: vulncheck.com
