CVE-2022-4092Public exploitNetwork attack vector

Browser data disclosure via unneutralized README input

Published Jan 24, 2023 · Updated Apr 1, 2025

Stored cross-site scripting in GitLab EE 15.6 allows remote authenticated users to expose data through a malicious README page. The README rendering path fails to neutralize user-supplied input before generating page content, allowing attacker-controlled script to run in a reader's browser. A low-privileged account must create the README and another user must view it; the published impact is browser-accessible data disclosure, not data modification or service interruption.
