Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
authentik is an open-source identity provider. Redirect URIs in the OAuth2 provider in authentik are checked by RegEx comparison. When no Redirect URIs are configured in a provider, authentik will automatically use the first redirect_uri value received as an allowed redirect URI, without escaping characters that have a special meaning in RegEx. Similarly, the documentation did not take this into consideration either. Given a provider with the Redirect URIs set to https://foo.example.com, an attacker can register a domain fooaexample.com, and it will correctly pass validation. authentik 2024.8.5 and 2024.10.3 fix this issue. As a workaround, When configuring OAuth2 providers, make sure to escape any wildcard characters that are not intended to function as a wildcard, for example replace `.` with `\.`.

Recommended fix High confidence

Authentik >= 2024.10.3 (or 2024.8.5 as minimum fix)

  1. Back up your current Authentik configuration and database
  2. Stop the Authentik service
  3. Pull the fixed Authentik image (2024.10.3 or later) or obtain the updated packages
  4. Update the Authentik installation to version 2024.10.3 (or 2024.8.5 as an alternative)
  5. Verify the service starts successfully
  6. Test OAuth2 provider redirect URI validation to confirm the fix is working
  7. As an additional precaution, review all OAuth2 providers and explicitly escape any special regex characters (e.g., replace . with \.) in Redirect URIs even though the code fix handles this automatically
