{"id":"CVE-2026-69254","aliases":["GHSA-3769-jgqc-cxm7"],"url":"https://o3.security/vulnerability/CVE-2026-69254","summary":"Flowise: RCE via NodeVM Sandbox Escape in executeJavaScriptCode() nodeVMOptions Override","details":"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.","published":"2026-08-04T15:28:49.651Z","modified":"2026-09-16T03:47:17.182023207Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"flowise","fixedVersion":"3.1.3"},{"ecosystem":"npm","name":"flowise-components","fixedVersion":"3.1.3"}],"fix":{"url":"https://github.com/FlowiseAI/Flowise/commit/3086cb7e323bb96c5a581d3232ef975b0d92183d","label":"FlowiseAI/Flowise@3086cb7"},"references":[{"type":"WEB","url":"https://github.com/FlowiseAI/Flowise/releases/tag/flowise@3.1.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/69xxx/CVE-2026-69254.json"},{"type":"ADVISORY","url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-3769-jgqc-cxm7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-69254"},{"type":"FIX","url":"https://github.com/FlowiseAI/Flowise/commit/3086cb7e323bb96c5a581d3232ef975b0d92183d"},{"type":"FIX","url":"https://github.com/FlowiseAI/Flowise/pull/6306"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T03:47:17.182023207Z"}}
