CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
Access to information you should not have access to when the permissions rely on $CURRENT_USER
for filtering.
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.
An example:
subscription {
directus_users_mutated {
event
data {
id
last_access
last_page
}
}
}
