How to Fix GHSA-jqwr-vx3p-r266

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.

n8n fixed: 1.123.67
npm install n8n@1.123.67
n8n fixed: 2.32.1
npm install n8n@2.32.1
n8n fixed: 2.31.5
npm install n8n@2.31.5
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

npm ls n8n

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-jqwr-vx3p-r266, inspect your project dependencies using npm:

npm ls n8n

Analyze 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 1.123.67), 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. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Impact The Postgres Trigger node interpolated user-supplied identifier parameters (channel, function, and trigger names) into SQL statements without proper escaping, so an authenticated user could inject arbitrary SQL executed against the connected PostgreSQL database with the configured credential's privileges. Successful exploitation allows full read and write access to the connected PostgreSQL database. ## Patches The issue has been fixed in n8n versions 1.123.67, 2.31.5 and 2.32.1. Users should upgrade to these versions or later to remediate the vulnerability. ## Workarounds If upgrading is not immediately possible, administrators should consider the following temporary mitigations: - Restrict n8n instance access to fully trusted users only. - Disable the PostgresTrigger node by adding `n8n-nodes-base.postgresTrigger` to the `NODES_EXCLUDE` environment variable. - Ensure PostgreSQL credentials used with n8n are configured with the minimum required privileges and do not use SUPERUSER roles. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
