| Description | Insufficient Session Expiration vulnerability in team-alembic ash_authentication_phoenix allows a session token captured before sign-out to remain usable afterwards. The default sign_out/2 that AshAuthentication.Phoenix.Controller injects into an application's auth controller only calls Plug.Conn.clear_session/1. It never revokes the stored session or bearer tokens, so a token obtained before sign-out, through script injection, interception or device theft, keeps authenticating until its own expiry. Changing the password still revokes it. This issue affects ash_authentication_phoenix: from 0.1.0 before 2.10.0. |
