CVE-2026-69254Public exploitNetwork attack vectorHinoki check available

Authenticated command execution via NodeVM option override

Published Aug 4, 2026 · Updated Aug 4, 2026

Code injection in Flowise before 3.1.3 allows remote authenticated users to execute arbitrary system commands through a custom function. executeJavaScriptCode() spreads caller-controlled nodeVMOptions over restricted NodeVM defaults, letting a nested call enable every built-in module and load child_process. A valid API key and access to the node-custom-function route are required; successful exploitation runs commands as root and exposes server files and stored secrets.
