CVE-2019-13006Network attack vector

Merge request count disclosure via missing repository check

Published Mar 10, 2020 · Updated Aug 4, 2024

Incorrect access control in GitLab CE and EE 9.0.0 through 12.0.2 allows remote authenticated users to view related merge request counts. The issue view exposes the count according to issue access without enforcing the repository-read permission protecting the referenced merge requests. An account that can view an issue but cannot access its repository can infer whether related merge requests exist, without viewing their contents.
