CVE-2023-39522

Reported by @markrassamni

Username enumeration attack

Summary

Using a recovery flow with an identification stage an attacker is able to determine if a username exists.

Patches

authentik 2023.5.6 and 2023.6.2 fix this issue.

Impact

Only setups configured with a recovery flow are impacted by this.

Details

An attacker can easily enumerate and check users' existence using the recovery flow, as a clear message is shown when a user doesn't exist. Depending on configuration this can either be done by username, email, or both.
