CVE-2025-2498Public exploitNetwork attack vector

Issue disclosure via REST API IP bypass

Published Aug 13, 2025 · Updated Aug 13, 2025

Improper access control in GitLab EE allows remote authenticated users to view assigned issues from IP-restricted groups through the REST API. The GET /api/v4/issues?scope=assigned_to_me path returns assigned issues without applying the top-level group's source-IP restriction. Reachability requires an assigned group member with an API token outside the allowed range; affected release lines begin at 12.0, 18.1, and 18.2.
