Both community and enterprise editions running on Node.js are impacted.<\/p>\n<p>Affected versions include:<\/p>\n<ul>\n<li>n8n versions before 1.123.67<\/li>\n<li>n8n versions before 2.31.5<\/li>\n<li>n8n versions before 2.32.1<\/li>\n<li>Specifically, n8n 2.32.0 (community and enterprise editions) is also affected.<\/li>\n<\/ul>\n<h2>Current Status<\/h2>\n<p>This vulnerability has been officially analyzed, and patches have been released to address the issue. Users are strongly advised to upgrade their n8n installations to a secure version as soon as possible.<\/p>\n<h2>Severity Level<\/h2>\n<p>The Common Vulnerability Scoring System (CVSS) assigns this vulnerability a score of 8.8, classifying it as **HIGH** severity. This indicates that the vulnerability is easily exploitable and could lead to significant data breaches or system compromise. While a GitHub advisory for this specific issue classified it as &#8220;Moderate&#8221; with a CVSS v4 score of 5.3, the CVE entry reflects a &#8220;HIGH&#8221; severity, which is generally a more comprehensive assessment. The risk primarily arises when workflow authors mistakenly embed untrusted, externally-controlled data directly into unparameterized SQL queries within the Snowflake node.<\/p>\n<h2>Possible Solutions<\/h2>\n<p>The developers of n8n have released patches to fix this SQL injection vulnerability.<\/p>\n<h3>Patched Versions:<\/h3>\n<p>Users should upgrade their n8n instance to one of the following versions or later:<\/p>\n<ul>\n<li>n8n version 1.123.67 or greater<\/li>\n<li>n8n version 2.31.5 or greater<\/li>\n<li>n8n version 2.32.1 or greater<\/li>\n<\/ul>\n<p>The fix introduces a new, optional &#8216;Query Parameters&#8217; field within the Snowflake node&#8217;s &#8216;Execute Query&#8217; operation. This field allows values to be safely bound using positional placeholders, preventing direct interpolation into the SQL string and thus mitigating the SQL injection risk.<\/p>\n<h3>Temporary Workarounds:<\/h3>\n<p>If an immediate upgrade is not feasible, consider these temporary mitigation steps:<\/p>\n<ul>\n<li><strong>Restrict Workflow Permissions:<\/strong> Limit who can create or edit workflows to only highly trusted users.<\/li>\n<li><strong>Audit Workflows:<\/strong> Carefully review existing workflows that utilize the Snowflake `executeQuery` operation. Ensure that no data controlled by external, untrusted sources is directly embedded into raw SQL query strings. Always use parameterized queries for dynamic data.<\/li>\n<li><strong>Network Access Control:<\/strong> Restrict network access to any webhook or trigger endpoints that feed data into Snowflake `executeQuery` nodes.<\/li>\n<\/ul>\n<p>It&#8217;s important to remember that these workarounds are only temporary measures and do not fully eliminate the risk. A full upgrade to a patched version is the most effective solution.<\/p>\n<h2>References<\/h2>\n<p>https:\/\/github.com\/n8n-io\/n8n\/security\/advisories\/GHSA-652q-gvq3-74qv<br
