CVE-2020-10956Network attack vector

Unauthenticated server-side requests via project-import notes

Published Mar 27, 2020 · Updated Aug 4, 2024

Server-side request forgery in GitLab 8.10 through 12.9 allows remote attackers to send server-originated requests through project-import notes. GitLab and the CVE record do not disclose the affected function or explain how a note-supplied value bypasses destination validation. The published record identifies no required account or user interaction, but it does not describe reachable destinations, response exposure, or resulting internal-system effects.
