Authenticated DoS via malicious file upload and repeated GraphQL queries in GitLab EE
In GitLab Enterprise Edition (EE), an issue affecting versions 15.6 before 18.6.6, 18.7 before 18.7.4, and 18.8 before 18.8.4 could allow an authenticated user to trigger a denial of service condition by uploading a malicious file and repeatedly querying it through GraphQL. The repeated GraphQL queries against the crafted uploaded content can exhaust server resources, resulting in service degradation or unavailability.
