CVE-2023-0223Network attack vector

Unauthenticated release-description disclosure via missing access check

Published Mar 9, 2023 · Updated Feb 28, 2025

Information disclosure in GitLab allows remote attackers to read project-member-only release descriptions through the Releases API. The API returns the description field without enforcing the project setting that restricts release visibility to project members. No authentication or user interaction is required on GitLab 15.5 through 15.7.7, 15.8 through 15.8.3, or 15.9 through 15.9.1; impact is limited to disclosure of release text.
