Disabled SSL verification in n8n

What this means (non-technical)
Disabled SSL verification means the HTTP Request node is set to ignore certificate errors. This allows connections to servers with invalid or self-signed certificates. While this can make testing easier, it removes an important safety check.
What usually goes wrong
Without certificate verification, your workflow cannot be sure it is talking to the real server.
An attacker positioned between your server and the target service could intercept or modify traffic.
This can result in:
API keys being captured.
Response data being altered.
Incorrect data flowing through your workflow.
The workflow may appear to function normally, but the connection is no longer trustworthy
When this becomes urgent
This becomes urgent when:
The workflow runs in production.
Sensitive data is transmitted.
The instance is hosted in shared or public infrastructure.
Compliance requirements apply.
Ignoring SSL issues temporarily during development is common. Leaving it disabled long term is where the risk grows.
