CVE-2023-38503Network attack vector

Authenticated data disclosure via unfiltered GraphQL subscriptions

Published Jul 25, 2023 · Updated Oct 10, 2024

Incorrect authorization in Directus 10.3.0 through 10.4.x allows remote authenticated users to read other users' subscription events. The GraphQL subscription generator read changed items without the subscriber's accountability, so $CURRENT_USER permission filters were not applied. A low-privileged account, a relevant subscription, and another user's record change are required; exposed fields can include user IDs, last access, and last page.
