CVE-2025-63388

A Cross-Origin Resource Sharing (CORS) misconfiguration vulnerability exists in Dify v1.9.1 in the /console/api/system-features endpoint. The endpoint implements an overly permissive CORS policy that reflects arbitrary Origin headers and sets Access-Control-Allow-Credentials: true, allowing any external domain to make authenticated cross-origin requests.
