Summary

GoCD is a continuous deliver server. From 18.7.0 until 26.1.0, the Get Template Config API compares HTTP method names case-sensitively when selecting authorization filters. A lower-privileged authenticated user can send a request with nonstandard HTTP method capitalization to retrieve a pipeline template by name without the required view permission and read its configuration. API operations that modify data are not affected, secure variables remain encrypted, and deployments whose reverse proxy rejects non-uppercase HTTP methods are not affected. This issue is fixed in version 26.1.0.
