Executive Summary

This vulnerability in GitLab CE/EE affects versions from 15.1 before 18.7.6, 18.8 before 18.8.6, and 18.9 before 18.9.2. Under certain conditions, it could allow an authenticated user to access previous pipeline job information on projects where the repository and CI/CD features are disabled. This happens due to improper authorization checks.

Impact Analysis

The impact of this vulnerability is that an authenticated user might gain unauthorized access to previous pipeline job information on certain GitLab projects. This could lead to unintended exposure of potentially sensitive pipeline data, even when repository and CI/CD are disabled.
