Short explanation

An SQL injection vulnerability exists in n8n via the Microsoft SQL node.

Why does it matter?

Unauthenticated external callers can execute arbitrary SQL against the connected database using stored credential privileges.

What should be done?

  • Follow vendor advisories
  • Avoid binding untrusted inputs to the Query field

Show the technical text from the sources

n8n before 2.41.4 and 2.42.x before 2.42.1 contains an SQL injection vulnerability in version 1 of the Microsoft SQL node, which substitutes Query field expression values directly into SQL text without parameterisation. When a workflow binds untrusted input such as webhook fields to the Query field, unauthenticated external callers can execute arbitrary SQL against the connected database with the stored credential's privileges.
