Analogy/Comparison

Imagine a security flaw in n8n is like leaving the front door to your smart home unlocked while your home assistant is set to do many important tasks. If a thief finds the unlocked door, they could sneak in and make your home assistant do anything they want, even things that could cause trouble.

Why It Matters

This issue is very important because n8n connects to many other online services and handles sensitive information. If someone exploits this flaw, they could steal secret data, change how your services work, or even run their own malicious programs on your system. For example, if a company uses n8n to manage customer data, an attacker could potentially access or alter that information.
