CVE-2026-55060 PUBLISHED

GoCD is vulnerable to authorization bypass via support process list API

Assigner: GitHub_M
Reserved: 16.06.2026 Published: 21.09.2026 Updated: 21.09.2026

GoCD is a continuous deliver server. From 13.1.0 until 26.1.0, the /go/api/support/process_list endpoint does not enforce its intended administrator-only authorization. An authenticated internal user can query the endpoint while source control child processes are running and view command-line arguments, usernames, remote material URLs, and internal material paths for materials the user cannot otherwise access. Exploitation depends on unpredictable process timing, and credentials, environment variables, and user-defined secrets remain masked or omitted. This issue is fixed in version 26.1.0.
