CVE-2026-55060: GoCD is vulnerable to authorization bypass via support process list API

• Severity: low (CVSS 3.7 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-09-21 · updated 2026-09-24
• Weakness: CWE-863

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.

Affected products

• gocd: from 13.1.0, < 26.1.0
