Summary

GitLab CE and EE from 15.0 before 19.3.6, from 19.4 before 19.4.3, and from 19.5 before 19.5.1 are affected. A viewer-independent fragment cache key causes per-user redacted content to be shared across all users, which exposes information cached in CWE-524. When a merge request in a public project references a confidential issue from a private project, an authenticated user with no project membership can read the confidential issue's title. CISA does not list the flaw in KEV, but the references include a public exploit link.

Description from the CNA

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 15.0 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, when a merge request in a public project referenced a confidential issue from a private project, an authenticated user with no project membership could have read the confidential issue's title, due to a viewer-independent fragment cache key that incorrectly shared per-user-redacted rendered content across all users.
