Detailsinfo

A vulnerability, which was classified as critical, was found in team-alembic ash_authentication up to 4.4.8. Affected is some unknown functionality. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Ash Authentication is an authentication framework for Elixir applications. Applications which have been bootstrapped by the igniter installer present since AshAuthentication v4.1.0 and who have used the magic link strategy _or_ are manually revoking tokens are affected by revoked tokens being allowed to verify as valid. Unless one hase implemented any kind of custom token revocation feature in your application, then one will not be affected. The impact here for users using builtin functionality is that magic link tokens are reusable until they expire. With that said, magic link tokens are only valid for 10 minutes, so the surface area for abuse is extremely low here. The flaw is patched in version 4.4.9. Additionally a compile time warning is shown to users with remediation instructions if they upgrade. 4.4.9 ships with an upgrader, so those who use `mix igniter.upgrade ash_authentication` will have the necessary patch applied. Otherwise, one may run the upgrader manually as described in the error message. As a workaround, delete the generated `:revoked?` generic action in the token resource. This will cause it to use the one internal to Ash Authentication which has always been correct. Alternatively, manually make the changes that are included in the patch.

The advisory is available at github.com. This vulnerability is traded as CVE-2025-25202 since 02/03/2025. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1068 by the MITRE ATT&CK project.

Upgrading to version 4.4.9 eliminates this vulnerability.
