Attackers can issue arbitrary GET and POST requests with attacker-controlled bodies via POST /api/v1/node-custom-function to reach loopback and internal-network addresses or the cloud metadata endpoint, enabling network mapping, credential disclosure, and state changes on internal services.","epss":null,"exploits":[{"kind":"exploit","source":"CNA: VulnCheck","url":"https://github.com/soovwv/cve/blob/main/research/flowise-ssrf-bypass-via-subpath-import.md"}],"kev":null,"metrics":[{"score":6.3,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:H/SI:L/SA:N","version":"4.0"},{"score":8.5,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N","version":"3.1"}],"modifiedAt":1794598044723,"publishedAt":1794598044723,"references":[{"source":"CNA: VulnCheck","tags":["technical-description","exploit"],"url":"https://github.com/soovwv/cve/blob/main/research/flowise-ssrf-bypass-via-subpath-import.md"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/flowise-ssrf-bypass-via-custom-function-sandbox"}],"remediation":[],"revision":"83b3c1ca641d91e6d0077cb0405aa6ada8dbb51a3ceb605168601fe1d7d18131","sources":[{"modifiedAt":1794598044723,"name":"CNA: VulnCheck","retrievedAt":1794600589986,"url":"https://www.cve.org/CVERecord?id=CVE-2026-127214"}],"ssvc":null,"status":"published","title":"Flowise 3.1.4 SSRF Bypass via Custom Function Sandbox","updatedAt":1794600589986}
