CVE-2025-53942 — Vulnerability in goauthentik.io — CVE Details

HIGH

Authentik has insufficient check for account active status when authenticating with OAuth/SAML Sources

Published July 22, 2025Updated April 17, 2026Source: osv

Summary

### Summary Deactivated users that had either enrolled via OAuth/SAML or had their account connected to an OAuth/SAML account can still partially access authentik even if their account is deactivated. They end up in a half-authenticated state where they cannot access the API but crucially they can authorize applications if they know the URL of the application. ### Patches authentik 2025.4.4 and 2025.6.4 fix this issue. ### Workarounds Adding an expression policy to the user login stage on the respective authentication flow with the expression of ```py return request.context["pending_user"].is_active ``` This expression will only activate the user login stage when the user is active. ### For more information If you have any questions or comments about this advisory: - Email us at [security@goauthentik.io](mailto:security@goauthentik.io).
