CVE-2025-0652 is an information disclosure vulnerability in GitLab CE and EE where internal notes associated with merge requests can be emailed to non-members when a review is submitted. The issue affects GitLab EE/CE versions starting from 16.9 before 17.7.7, 17.8 before 17.8.5, and 17.9 before 17.9.2. Because internal notes are intended for restricted internal use, the flaw can expose confidential merge request discussion content to unauthorized recipients outside the intended membership boundary.
