Information disclosure via reflected credentialed CORS
Published Dec 18, 2025 · Updated Dec 18, 2025
CORS misconfiguration in Dify 1.9.1 allows remote attackers to read system configuration through cross-origin requests. The /console/api/system-features endpoint reflects any Origin value while enabling credentials, so a requesting origin can read its response. The supplier disputes the security impact because credentialed requests provide no access beyond the endpoint's unauthenticated response.
