n8n: Snowflake Node executeQuery Operation Allows SQL Injection via Unparameterized Expression Interpolation — n8n

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Impact

The n8n Snowflake node's Execute Query operation interpolated expression values directly into the SQL string, making queries built with untrusted data susceptible to SQL injection.

Exploitation requires that a workflow author has already embedded untrusted expression data directly in a raw SQL query.

Patches

The issue has been fixed in n8n versions 1.123.67, 2.31.5, and 2.32.1. Users should upgrade to one of these versions or later to remediate the vulnerability. The fix introduces an optional "Query Parameters" field that allows values to be bound via positional placeholders rather than interpolated into the query string.

Workarounds

If upgrading is not immediately possible, administrators should consider the following temporary mitigations:

  • Restrict workflow creation and editing permissions to fully trusted users only.
  • Audit existing workflows that use the Snowflake executeQuery operation and ensure no expression resolving to externally-controlled data is embedded directly in a raw SQL query string.
  • Restrict network access to any webhook or trigger endpoints that feed data into Snowflake executeQuery nodes.

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.

Frequently Asked Questions

A security vulnerability is a weakness in software, hardware, or configuration that can be exploited to compromise confidentiality, integrity, or availability. Many vulnerabilities are tracked as CVEs (Common Vulnerabilities and Exposures), which provide a standardized identifier so teams can coordinate patching, mitigation, and risk assessment across tools and vendors.

CVSS (Common Vulnerability Scoring System) estimates technical severity, but it doesn't automatically equal business risk. Prioritize using context like internet exposure, affected asset criticality, known exploitation (proof-of-concept or in-the-wild), and whether compensating controls exist. A "Medium" CVSS on an exposed, production system can be more urgent than a "Critical" on an isolated, non-production host.

A vulnerability is the underlying weakness. An exploit is the method or code used to take advantage of it. A zero-day is a vulnerability that is unknown to the vendor or has no publicly available fix when attackers begin using it. In practice, risk increases sharply when exploitation becomes reliable or widespread.

Recurring findings usually come from incomplete Asset Discovery, inconsistent patch management, inherited images, and configuration drift. In modern environments, you also need to watch the software supply chain: dependencies, containers, build pipelines, and third-party services can reintroduce the same weakness even after you patch a single host. Unknown or unmanaged assets (often called Shadow IT) are a common reason the same issues resurface.

Use a simple, repeatable triage model: focus first on externally exposed assets, high-value systems (identity, VPN, email, production), vulnerabilities with known exploits, and issues that enable remote code execution or privilege escalation. Then enforce patch SLAs and track progress using consistent metrics so remediation is steady, not reactive.

SynScan combines attack surface monitoring and continuous security auditing to keep your inventory current, flag high-impact vulnerabilities early, and help you turn raw findings into a practical remediation plan.
