{"id":"CVE-2026-69254","published":"2026-08-04T16:16:29.243","lastModified":"2026-08-04T19:16:53.613","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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-94"],"vendors":[],"products":[],"references":[{"url":"https://github.com/FlowiseAI/Flowise/commit/3086cb7e323bb96c5a581d3232ef975b0d92183d","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/pull/6306","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/releases/tag/flowise@3.1.3","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-3769-jgqc-cxm7","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-3769-jgqc-cxm7","tags":[]}],"exploitRefs":[{"url":"https://github.com/FlowiseAI/Flowise/commit/3086cb7e323bb96c5a581d3232ef975b0d92183d","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/pull/6306","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/releases/tag/flowise@3.1.3","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-3769-jgqc-cxm7","tags":[]},{"url":"https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-3769-jgqc-cxm7","tags":[]}],"hasPoc":true,"ai":null}
