1) Improper Authorization (CVE-ID: N/A)

CWE-ID: CWE-285 - Improper Authorization

CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to disclose sensitive information.

The vulnerability exists due to improper authorization in native GraphQL element-to-user relations when resolving related user fields through GraphQL queries. A remote user can query author, authors, uploader, draftCreator, or revisionCreator fields to disclose sensitive information.

The issue affects user-group scoping for related user records and can expose usernames, email addresses, and full names outside the intended GraphQL schema scope.
