I need to understand the security risks of exposing the Node.js debugger port publicly and find the recommended safe practices for enabling remote debugging. What are the key security implications, and what specific advice does the Node.js documentation provide to safely allow remote debugger clients to connect?
Navigate to 'nodejs.org'. Go to the 'Learn' section. Locate and navigate to the 'Debugging Node.js' page. Identify the section discussing 'Security Implications'. Extract the warnings and risks associated with exposing the debug port publicly. Find the specific advice or link related to 'Enabling remote debugging scenarios'. Summarize the key security implications and the recommended approach for safe remote debugging.
State that the debugger has full access to the Node.js execution environment, allowing a malicious actor to execute arbitrary code if connected. Mention that exposing the debug port publicly (binding to a public IP or 0.0.0.0) is unsafe and allows unrestricted connection. Confirm that by default, `--inspect` binds to `127.0.0.1` for security reasons. Refer to the advice about ensuring appropriate firewalls and access controls are in place to prevent security exposure for remote debugging scenarios, and specifically mention the recommendation to use SSH tunnels instead of public IP binding.
