Prior to 3.1.3, the OAuth2 token refresh endpoint POST /api/v1/oauth2-credential/refresh/:credentialId is unauthenticated by design and performs a server-side HTTP request to the credential-controlled accessTokenUrl without SSRF protections. Runtime validation confirmed that the endpoint was reachable without authentication, triggered outbound POST requests to an attacker-controlled server, reflected the full remote response body to the caller through tokenInfo, and sent client_id, client_secret, grant_type=refresh_token, and refresh_token in the request body. This issue is fixed in version 3.1.3.","state":0,"publishedAt":"2026-08-04T14:20:35.395+00:00","modifiedAt":"2026-08-04T19:52:53.398+00:00","affected":[{"ecosystem":"Vendor product","name":"Flowise","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"FlowiseAI\",\n                    \"product\": \"Flowise\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 3.1.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.5,"severity":"HIGH"}],"references":["https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-r745-8hwv-h473","https://github.com/FlowiseAI/Flowise/commit/da8b251a9a4c59484ceaf6f71df7406aede7bef2","https://github.com/FlowiseAI/Flowise/releases/tag/flowise@3.1.3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-69250","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-69250","identifiers":["CVE-2026-69250"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
