CVE-2026-52740 · Severity: info · Published 2026-09-21

GoCD is a continuous deployment server that manages automated software delivery pipelines. An authenticated user with limited permissions can retrieve pipeline template configurations they should not have access to by using non-standard capitalization in HTTP request methods. While this does not allow modifying data or exposing encrypted secrets, it enables unauthorized information disclosure of pipeline template details.

## Technical details

The Get Template Config API performs case-sensitive comparison of HTTP method names when selecting authorization filters, allowing an authenticated attacker to bypass permission checks by submitting requests with mixed-case or non-uppercase HTTP method names (e.g., "Get" instead of "GET"). This enables reading pipeline template configurations without the required view permission. The vulnerability only affects read operations; deployments using reverse proxies that normalize HTTP methods to uppercase are unaffected, and secure variables remain encrypted.
