CVE-2023-39522
Withdrawn Advisory: Username enumeration attack in goauthentik
Summary
### Withdrawn Advisory This advisory has been withdrawn due to an incorrect package mapping error. This link is maintained to preserve external references. ### Original Description ## Summary Using a recovery flow with an identification stage an attacker is able to determine if a username exists. ## Impact Only setups configured with a recovery flow are impacted by this. Anyone with a user account on a system with the recovery flow described above is susceptible to having their username/email revealed as existing. ## 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. The invalid and valid usernames should both show the same message and always send an email.
