CVE-2026-69254 Details
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.
A remote code execution vulnerability has been identified in Flowise, a user interface for building customized large language model flows. This issue affects Flowise versions 3.0.5 prior to 3.1.2. The vulnerability arises in the 'executeJavaScriptCode()' function, which allows authenticated users to override default security settings and execute arbitrary system commands as root on the Flowise server. Exploitation involves bypassing module restrictions to access blocked Node.js built-in modules, such as 'child_process', and using them to execute commands with elevated privileges.
Users can upgrade to Flowise version 3.1.3, where this vulnerability has been patched.
