CVE-2020-10077Network attack vector

Unauthenticated SSRF via undisclosed deprecated service

Published Mar 13, 2020 · Updated Aug 4, 2024

Server-side request forgery in GitLab EE 3.0 through 12.8.1 allows remote attackers to make server-originated network requests. GitLab identifies the locus only as a deprecated service and has not disclosed the endpoint, input flow, or missing validation that permits the requests. No authentication or user interaction is required; the server can reach unintended services, while the vendor has not bounded the data or state exposed through those requests.
