n8n-nodes-rce-pocnpm
Malicious code in n8n-nodes-rce-poc (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
On require by n8n (module-load, top-level code in dist/RceNode.node.js), the package runs a shell command via execSync('/bin/sh',...). The command is taken from process.env.__N8N_RCE_CMD with a default of 'id && hostname && uname -a', so even an unconfigured install shells out and leaks host identity at load time, in the n8n host process and outside the vm2 sandbox. When process.env.__N8N_RCE_CB is set and EXEC_MODE is 'webhook' or 'both', the executed command's stdout/stderr/exitCode are serialized to JSON and HTTP-POSTed to the URL specified in __N8N_RCE_CB (dist/RceNode.node.js:28-40), giving a complete env-driven exfiltration channel to any destination. The node also exposes an execute() method that runs arbitrary user-supplied shell commands via /bin/sh on the n8n host, breaking the workflow Code-node sandbox model. The package.json description self-identifies as an 'n8n RCE proof-of-concept node'. There is no benign installer use: any n8n instance that installs this gains a drop-in remote-code-execution primitive plus a configurable exfiltration callback.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for n8n-nodes-rce-poc (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging n8n-nodes-rce-poc across your stack and pipelines.
If you installed it — respond
n8n-nodes-rce-poc is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If n8n-nodes-rce-poc was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks n8n-nodes-rce-poc before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
