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."},{"lang":"es","value":"Flowise es una interfaz de usuario de arrastrar y soltar para construir un flujo de modelo de lenguaje grande personalizado. Antes de la versión 3.1.0, existe una vulnerabilidad de falsificación de petición del lado del servidor (SSRF) en los componentes de cadena de API POST/GET de FlowiseAI que permite a atacantes no autenticados forzar al servidor a realizar peticiones HTTP arbitrarias a sistemas internos y externos. Al inyectar plantillas de prompt maliciosas, los atacantes pueden eludir las restricciones de la documentación de la API previstas y redirigir peticiones a servicios internos sensibles, lo que podría llevar a reconocimiento de red interno y exfiltración de datos. Esta vulnerabilidad se ha corregido en la versión 3.1.0."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"FlowiseAI","product":"Flowise","versions":[{"version":"< 3.1.0","status":"affected"}]},{"vendor":"FlowiseAI","product":"flowise-components","versions":[{"version":"< 3.1.0","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L","baseScore":8.3,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"LOW"},"exploitabilityScore":2.8,"impactScore":5.5}],"cvssMetricV30":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:L","baseScore":7.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"LOW"},"exploitabilityScore":1.6,"impactScore":5.5}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-04-23T19:45:41.723100Z","id":"CVE-2026-41271","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-918"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:flowiseai:flowise:*:*:*:*:*:*:*:*","versionEndExcluding":"3.1.0","matchCriteriaId":"CB30DB8F-4F72-4FD3-90FB-8331F1CBB78E"}]}]}],"references":[{"url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-6r77-hqx7-7vw8","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]},{"url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-6r77-hqx7-7vw8","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Vendor Advisory"]}]}
