{"id":"CVE-2026-31829","aliases":["GHSA-fvcw-9w9r-pxc7"],"url":"https://o3.security/vulnerability/CVE-2026-31829","summary":"Flowise affected by Server-Side Request Forgery (SSRF) in HTTP Node Leading to Internal Network Access","details":"Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.0.13, Flowise exposes an HTTP Node in AgentFlow and Chatflow that performs server-side HTTP requests using user-controlled URLs. By default, there are no restrictions on target hosts, including private/internal IP ranges (RFC 1918), localhost, or cloud metadata endpoints. This enables Server-Side Request Forgery (SSRF), allowing any user interacting with a publicly exposed chatflow to force the Flowise server to make requests to internal network resources that are inaccessible from the public internet. This vulnerability is fixed in 3.0.13.","published":"2026-03-10T21:43:58.549Z","modified":"2026-08-07T11:31:18.014560130Z","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"flowise","fixedVersion":"3.0.13"},{"ecosystem":"npm","name":"flowise-components","fixedVersion":"3.0.13"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31829.json"},{"type":"ADVISORY","url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-fvcw-9w9r-pxc7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31829"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:18.014560130Z"}}
