CVE-2026-33713: N8n SQL Injection Vulnerability
HIGHCVE-2026-33713 is a HIGH (CVSS 9.9) sql injection vulnerability (CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')) affecting N8n libraries in the npm ecosystem. The issue involves n8n has sql injection in data table node via orderbycolumn expression. Remediation is available by upgrading affected packages to version 1.123.26, 2.14.1, 2.13.3.

Security Impact
CVSS: 9.9
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
How to Fix CVE-2026-33713
To remediate this vulnerability, upgrade all affected N8n dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install n8n@1.123.26npm install n8n@2.14.1npm install n8n@2.13.3Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls n8nHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2026-33713, inspect your project dependencies using npm:
npm ls n8nAnalyze the terminal output to locate any version of N8n in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.123.26), your application is affected.
Note: The npm ls n8n command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In N8n, software state validation or input boundaries are circumvented during processing.

"details" : "## Impact\nAn authenticated user with permission to create or modify workflows could exploit a SQL injection vulnerability in the Data Table Get node. On default SQLite DB, single statements can be manipulated and the attack surface is practically limited. On PostgreSQL deployments, multi-statement execution is possible, enabling data modification and deletion.\n\n## Patches\nThe issue has been fixed in n8n versions 1.123.26, 2.13.3, and 2.14.1. Users should upgrade to one of these versions or later to remediate the vulnerability.\n\n## Workarounds\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Limit workflow creation and editing permissions to fully trusted users only.\n- Disable the Data Table node by adding `n8n-nodes-base.dataTable` to the `NODES_EXCLUDE` environment variable.\n- Review existing workflows for Data Table Get nodes where `orderByColumn` is set to an expression that incorporates external or user-supplied input.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.",
