Summary Duplicate Advisory: Flowise contains an unauthenticated sandbox escape # Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-9gvv-qjj3-2p6g. This link is maintained to preserve external references. # Original Description Flowise (packages flowise and flowise-components) in versions <= 3.1.2 contain a sandbox escape in the `vm2/@flowiseai/nodevm` JavaScript sandbox. An authenticated user with access to the `/api/v1/node-custom-function` endpoint can escape the sandbox by supplying attacker-controlled executablePath and args parameters to puppeteer.launch(), which internally invokes child_process.spawn() outside the sandbox boundary. This allows execution of arbitrary OS commands as the Flowise process user (root in the official Docker image) and arbitrary host file disclosure via Chromium's `file://` URL handling. In versions 3.0.8–3.1.2 exploitation requires `ALLOW_BUILTIN_DEP=true`; earlier versions are exploitable by default. Fixed in 3.1.3.
