**Name of the Vulnerable Software and Affected Versions** authentik versions prior to 2023.8.4 and 2023.10.2 **Description** authentik is an open-source Identity Provider. When the default admin user has been deleted, it is potentially possible for an attacker to set the password of the default admin user without any authentication. authentik uses a blueprint to create the default admin user, which can also optionally set the default admin user's password from an environment variable. The `initial-setup` flow used to configure authentik after the first installation becomes available again when the user is deleted. **Recommendations** To resolve the issue, update to version 2023.8.4 or 2023.10.2. As a temporary workaround, ensure the default admin user (Username `akadmin`) exists and has a password set. It is recommended to use a very strong password for this user, and store it in a secure location like a password manager. It is also possible to deactivate the user to prevent any logins as `akadmin`.
