CVE-2019-13121Public exploitNetwork attack vector

Internal-network requests via unchecked redirects

Published Mar 10, 2020 · Updated Aug 4, 2024

SSRF in GitLab Enterprise Edition 10.6 through 12.0.2 allows attackers to send requests to local network resources via GitHub integration. The GitHub service follows an attacker-controlled redirect and sends an arbitrary POST request without revalidating the redirected destination. The published reproduction requires a signed-in user who can create a project; successful abuse uses the GitLab server as a path to otherwise unreachable internal services.
