GitLab Community Edition and Enterprise Edition: attackers can read or change files
OFFICIAL NAME: GitLab Community Edition and Enterprise Edition Path Traversal Vulnerability
WHAT IT IS · DEVELOPER TOOLSIt holds source code and the keys used to build and ship software.
DO THIS FIRSTPatch it. If it faced the internet, change the keys and passwords stored in it. Not sure if you use it? Send this page to your IT provider or security lead and ask.
TECHNICAL SUMMARY GitLab Community Edition and Enterprise Edition contains a path traversal vulnerability that allows an unauthenticated user to read arbitrary files due to an improper path confinement and missing authentication enforcement in the repository commits API.
WHY THIS VERDICT Attacks are confirmed. The vulnerability is 59 days old, so many systems are likely still unpatched. Ready-made attack tools are public. The severity score is critical (10.0). The exploit prediction score is 97%.
WHY IT RANKS HERE Exploitation is confirmed by an authoritative source. Ready-made attack tools are public.

THE FIX
CISA's instruction: apply the vendor's fix, or stop using the product if no fix exists. The deadline CISA set for US federal agencies, Sep 14, 2026, has passed. It is a US government deadline; use it as a guide.
Questions to ask this week
- Do we run GitLab Community Edition and Enterprise Edition? If yes, is it patched or cut off from the internet?
- Who owns fixing it, and by what date?
- Have we checked for signs of attack since the first report, not just since the patch?
