DescriptionCVE.org
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.
