CVE-2025-63388 describes a critical Cross-Origin Resource Sharing (CORS) misconfiguration in Dify v1.9.1, specifically affecting the /console/api/system-features endpoint. This vulnerability allows any external domain to make authenticated cross-origin requests due to an overly permissive CORS policy that reflects arbitrary Origin headers and sets Access-Control-Allow-Credentials: true. With a CVSS score of 9.1 (CRITICAL), this network-exploitable vulnerability requires no user interaction and could lead to high confidentiality and integrity impacts. While the vendor disputes the severity, arguing no additional access is gained, there is no known active exploitation, public exploit code, or Metasploit/Nuclei modules available. However, the vulnerability has garnered significant community discussion, with 10 mentions, indicating considerable attention.
