Cross-product issue disclosure via unchecked issue key
Published Oct 17, 2022 · Updated May 14, 2025
Authorization bypass in affected GitLab EE releases allows remote authenticated users to read unrelated ZenTao project issues. The issue-detail route accepts an attacker-controlled ZenTao issue key and fetches it without verifying that the issue belongs to the product ID configured for the GitLab project. Access to a GitLab project with the premium ZenTao integration is normally required, although a public project exposes the route without authentication; successful enumeration discloses issues from other ZenTao products available to the configured API key.
