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.

Suggested hunting (rule-based inference)
SecOps Signal recommendation (rule-based inference). These steps are hunting hypotheses from the vulnerability class; they do not state or imply that exploitation occurred here or anywhere.
Matched sql-injection (CWE-89); network-unauthenticated (CVSS AV:N, CVSS PR:N, CVSS UI:N)
Exposure
- Locate the affected application endpoint and confirm its deployed version.Telemetry: Application access logs · The CWE describes a weakness class, not which local endpoint is affected. · Rule sql-injection
- Identify devices reporting this CVE and note which expose the affected service to untrusted networks.Telemetry: DeviceTvmSoftwareVulnerabilities · A network-reachable, no-privilege vector makes internet-facing instances the first exposure question. · Rule network-unauthenticated
Exploitation evidence
- Review requests to the affected endpoint for unusual query syntax and response anomalies.Telemetry: Application access logs · Request and error patterns can guide an SQL injection investigation. · Rule sql-injection

Exploitation evidence
- Review inbound connections to the affected service from unexpected sources since the advisory date.Telemetry: DeviceNetworkEvents · Hunting hypothesis from the CVSS vector; it does not show that exploitation occurred. · Rule network-unauthenticated
Response
- Verify the source-stated fix and test the affected endpoint after deployment.Telemetry: Application change records · The exact application fix must be confirmed locally. · Rule sql-injection
