## FAQ

### What does this mean?

The login flow accepts an authenticator-app two-factor code without first checking the account password. Someone holding a user's current authenticator code could log in as that user, including an administrator, without knowing the password.

### Is it 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.
