What is CVE-2026-55060?
CVE-2026-55060 is a low-severity missing authorization vulnerability in gocd, published on 21 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-863
