Name of the Vulnerable Software and Affected Versions Dify version 1.9.1

Description A Cross-Origin Resource Sharing (CORS) misconfiguration exists in the /console/api/system-features endpoint. The endpoint has an overly permissive CORS policy that reflects arbitrary Origin headers and sets Access-Control-Allow-Credentials to true, potentially allowing any external domain to make authenticated cross-origin requests.

Recommendations Apply a restrictive CORS policy to the /console/api/system-features endpoint to only allow requests from trusted origins.
