Summary
In Directus, from version 10.3.0 to 10.5.0, permission filters are not properly checked when using GraphQL subscriptions. This leads to unauthorized users receiving events they should not have access to.
Risk Assessment
The organization may be exposed to data leaks, as users can receive updates about other users, violating privacy and security policies.
Recommendation
It is recommended to upgrade Directus to version 10.5.0, which contains a patch. Alternatively, GraphQL subscriptions can be temporarily disabled.
Original NVD description (English source)
Directus is a real-time API and App dashboard for managing SQL database content. Starting in version 10.3.0 and prior to version 10.5.0, the permission filters (i.e. `user_created IS $CURRENT_USER`) are not properly checked when using GraphQL subscription resulting in unauthorized users getting event on their subscription which they should not be receiving according to the permissions. This can be any collection but out-of-the box the `directus_users` collection is configured with such a permissions filter allowing you to get updates for other users when changes happen. Version 10.5.0 contains a patch. As a workaround, disable GraphQL subscriptions.
