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. NOTE: the Supplier disputes this, providing the rationale of \"sending requests with credentials does not provide any additional access compared to unauthenticated requests.\"","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1},"cwes":["CWE-346"],"references":["https://gist.github.com/Cristliu/5ded6d03e41d7d66ecb1b568bae3ff6c","https://gist.github.com/Cristliu/c2bc7d05abd89db8eb542a453a528d77","https://github.com/langgenius/dify/discussions"],"products":["langgenius:dify"],"source":"nvd","synced_at":"2026-10-19T22:17:07.138532058+00:00"},"epss":{"cve":"CVE-2025-63388","score":0.00222,"percentile":0.12597,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
