CVE-2022-0751Public exploitNetwork attack vector

User command execution via hidden snippet files

Published Mar 28, 2022 · Updated Aug 2, 2024

Improper output neutralization in affected GitLab releases allows remote authenticated users to induce command execution via Snippets. The web interface omits files whose names contain non-printable ASCII characters even though cloned repositories retain them, allowing a benign-looking filename to resolve to a hidden symlinked payload. Exploitation requires permission to create and push a snippet and a victim who clones it and runs the presented command; execution occurs on the victim's host.
