Dify 1.9.1 and 1.17.0 exposes the /console/api/system-features endpoint to unauthenticated HTTP GET requests that return system feature and configuration information.

They also state that the data is non-sensitive and required for client-side rendering. No PII, credentials, or secrets are exposed.
