CVE-2021-44659Network attack vector

Server-side request forgery via pipeline configuration

Published Dec 22, 2021 · Updated Aug 4, 2024

SSRF in GoCD Server 21.3.0 allows remote authenticated users to make server-originated requests through new pipeline configuration. The new-pipeline workflow accepts an administrator-selected outbound destination and directs the server to contact it without restricting that destination. GoCD disputes the vulnerability because only administrators can configure these outbound requests, and no additional consequence is established.
