Suspended Directus user can continue to use session token to access API

Summary

Since the user status is not checked when verifying a session token a suspended user can use the token generated in session auth mode to access the API despite their status.

Details

There is a check missing in verifySessionJWT to verify that a user is actually still active and allowed to access the API. Right now one can extract the session token obtained by, e.g. login in to the app while still active and then, after the user has been suspended continue to use that token until it expires.

PoC

• Create an active user
• Log in with that user and note the session cookie
• Suspend the user (and don't trigger an /auth/refresh call, as that invalidates the session
• Access the API with Authorization: Bearer <token>

Impact

This weakens the security of suspending users.
