CVE-2026-55060Network attack vectorHinoki check available

Authenticated process information disclosure via missing admin check

Published Sep 21, 2026 · Updated Sep 21, 2026

Incorrect authorization in Thoughtworks GoCD 13.1.0 through 25.4.0 allows remote authenticated users to read process details. The /go/api/support/process_list endpoint authenticates callers but omits its intended administrator-role check before returning child-process metadata. Disclosure requires a source-control process to be running and is limited to command arguments, usernames, remote URLs, and internal paths; credentials and secrets remain masked.
