Description

authentik is an open-source Identity Provider that emphasizes flexibility and versatility, with support for a wide set of protocols. In versions 2025.4.4 and earlier, as well as versions 2025.6.0-rc1 through 2025.6.3, deactivated users who registered through OAuth/SAML or linked their accounts to OAuth/SAML providers can still retain partial access to the system despite their accounts being 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. To workaround this issue, developers can add an expression policy to the user login stage on the respective authentication flow with the expression of return request.context["pending_user"].is_active. This modification ensures that the return statement only activates the user login stage when the user is active. This issue is fixed in versions authentik 2025.4.4 and 2025.6.4.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for goauthentik.io, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update goauthentik.io to 0.0.0-20250722122105-7a4c6b9b50f8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-53942 is resolved across your whole dependency graph.

  3. Workarounds

    Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable.
