{"cve":"CVE-2025-71334","nvd":{"published":"2026-06-25T22:16:59.127","modified":"2026-10-12T21:10:00.227","status":"Analyzed","description":"Flowise before 3.0.6 (affected versions 2.2.8 and earlier) contains an arbitrary file access vulnerability due to missing validation that the chatflowId and chatId parameters are UUIDs or numbers in file handling operations. By supplying a path-traversal value (e.g., '../../../../../tmp') as the chatflow id, an unauthenticated attacker can use the /api/v1/chatflows endpoint (via addBase64FilesToStorage) to write arbitrary files, and the /api/v1/get-upload-file and /api/v1/openai-assistants-file/download endpoints (via streamStorageFile) to read arbitrary files. Arbitrary file write may lead to remote code execution.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-73"],"references":["https://github.com/FlowiseAI/Flowise/commit/8bd3de41533de78e4ef6c980e5704a1f9cb7ae6f","https://github.com/FlowiseAI/Flowise/commit/c2b830f279e454e8b758da441016b2234f220ac7","https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-q67q-549q-p849","https://www.vulncheck.com/advisories/flowise-arbitrary-file-access-via-missing-chat-flow-id-validation","https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-q67q-549q-p849"],"products":["flowiseai:flowise"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2025-71334","score":0.0436,"percentile":0.91176,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-q67q-549q-p849","url":"https://osv.dev/vulnerability/GHSA-q67q-549q-p849","summary":"Flowise has arbitrary file access due to missing chat flow id validation","modified":"2026-07-08T07:10:54.304581197Z","packages":[{"ecosystem":"npm","name":"flowise","purl":"pkg:npm/flowise","ranges":[">=2.2.8 <3.0.6"],"fixed":["3.0.6"]}]}],"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).
