Prior to 3.1.0, a Server-Side Request Forgery (SSRF) vulnerability exists in FlowiseAI's POST/GET API Chain components that allows unauthenticated attackers to force the server to make arbitrary HTTP requests to internal and external systems. By injecting malicious prompt templates, attackers can bypass the intended API documentation constraints and redirect requests to sensitive internal services, potentially leading to internal network reconnaissance and data exfiltration. This vulnerability is fixed in 3.1.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L","score":8.3},"cwes":["CWE-918"],"references":["https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-6r77-hqx7-7vw8","https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-6r77-hqx7-7vw8"],"products":["flowiseai:flowise"],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-41271","score":0.00233,"percentile":0.14029,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-6r77-hqx7-7vw8","url":"https://osv.dev/vulnerability/GHSA-6r77-hqx7-7vw8","summary":"Flowise:  APIChain Prompt Injection SSRF in GET/POST API Chains","modified":"2026-05-05T16:11:38.778571Z","packages":[{"ecosystem":"npm","name":"flowise","purl":"pkg:npm/flowise","ranges":["<3.1.0"],"fixed":["3.1.0"]},{"ecosystem":"npm","name":"flowise-components","purl":"pkg:npm/flowise-components","ranges":["<3.1.0"],"fixed":["3.1.0"]}]}],"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).
