CVE-2023-5117Network attack vector

Unauthenticated attachment disclosure via project-level access policy

Published Dec 25, 2024 · Updated Dec 26, 2024

Information disclosure in GitLab CE/EE before 17.6.0 allows remote attackers to read confidential attachments through direct URLs. The upload-serving path applies public project or group visibility instead of the confidentiality policy of the parent issue or epic. An attacker must obtain the randomized 32-character upload URL; disclosure is limited to the referenced file, with no reported write access.
