Authentication Bypass Gitlab

Description

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.2 before 18.8.9, 18.9 before 18.9.5, and 18.10 before 18.10.3 that could have allowed an authenticated user to access confidential issues assigned to other users via CSV export due to insufficient authorization checks.

Analysis

GitLab CE/EE versions 18.2-18.10.2 allow authenticated users to export confidential issues assigned to other users via CSV export due to missing authorization validation. The vulnerability affects approximately three release branches with a moderate CVSS score of 4.3, limited by the requirement for prior authentication and lack of integrity impact, but represents a direct confidentiality breach in multi-tenant environments where issue classification is a security boundary.
