Alert meAnalysisAIv1 – Sep 15, 2026
Authenticated users of GitLab CE/EE can read CI/CD variables that are scoped to environments they are not entitled to, because the environment scope pattern matcher fails to validate scope input correctly. The flaw affects all versions from 15.7 up to 19.1.7, 19.2.5, and 19.3.1, with fixes in 19.1.8, 19.2.6, and 19.3.2. Public exploit code exists (referenced via a HackerOne report), the issue carries a CVSS of 7.7 with a confidentiality-only, scope-changed profile, and there is no CISA KEV listing indicating confirmed active exploitation at time of analysis.
