{"cve":"CVE-2026-69254","nvd":{"published":"2026-08-04T16:16:29.243","modified":"2026-10-23T23:10:00.157","status":"Analyzed","description":"Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, executeJavaScriptCode() accepted caller-provided nodeVMOptions and merged them over the default NodeVM security settings in packages/components/src/utils.ts. An authenticated attacker reaching packages/server/src/routes/node-custom-functions/index.ts could run a custom function that imported flowise-components/dist/src/utils.js, called executeJavaScriptCode() again with nodeVMOptions.require.builtin set to allow all built-in modules, and then required child_process to execute arbitrary system commands as root on the Flowise server. This issue is fixed in version 3.1.3.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":9.4},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-94"],"references":["https://github.com/FlowiseAI/Flowise/commit/3086cb7e323bb96c5a581d3232ef975b0d92183d","https://github.com/FlowiseAI/Flowise/pull/6306","https://github.com/FlowiseAI/Flowise/releases/tag/flowise@3.1.3","https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-3769-jgqc-cxm7","https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-3769-jgqc-cxm7"],"products":["flowiseai:flowise"],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-69254","score":0.00691,"percentile":0.5254,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-3769-jgqc-cxm7","url":"https://osv.dev/vulnerability/GHSA-3769-jgqc-cxm7","summary":"Flowise: RCE via NodeVM Sandbox Escape in executeJavaScriptCode() nodeVMOptions Override","modified":"2026-08-04T15:56:02.787653Z","packages":[{"ecosystem":"npm","name":"flowise","purl":"pkg:npm/flowise","ranges":["<3.1.3"],"fixed":["3.1.3"]},{"ecosystem":"npm","name":"flowise-components","purl":"pkg:npm/flowise-components","ranges":["<3.1.3"],"fixed":["3.1.3"]}]}],"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).
