CVE-2026-55632: Gocd

Medium severity, CVSS 4.3. EPSS: 0.3% chance of exploitation in the next 30 days.

GoCD is a continuous deliver server. From 20.2.0 until 26.1.0, the internal pipeline structure API used for autocompletion while editing pipeline, template, environment, and user-preference configuration returns its users-and-roles mode to regular authenticated users without requiring an administrator role. A lower-privileged user can enumerate configured user names and available role names, which can facilitate attacks against those users. The response does not reveal which roles are assigned to each user, and the endpoint cannot modify data. This issue is fixed in version 26.1.0.

Affected products

• Gocd Gocd: from 20.2.0, before 26.1.0 (fixed in 26.1.0)
