Description

This module exploits a critical remote code execution vulnerability (CVE-2025-68613)
in the n8n workflow automation platform. The vulnerability exists in the workflow
expression evaluation system where user-supplied expressions enclosed in {{ }}
are evaluated in an execution context that is not sufficiently isolated from the
underlying Node.js runtime.

An authenticated attacker can create a workflow containing malicious expressions
that access the Node.js process object via this.process.mainModule.require (or via
the constructor) to load child_process and execute arbitrary system commands.
This module uses a Schedule Trigger node to automatically fire and evaluate the
malicious payload. This requires valid credentials to create workflows.

Successful exploitation may lead to full compromise of the n8n instance,
including unauthorized access to sensitive data, modification of workflows,
and execution of system-level operations.
