How to Fix GHSA-6qc9-mqvw-jg7x

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-6qc9-mqvw-jg7x, 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-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. 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 An authenticated member with edit access to a shared workflow could reference another user's credential in an HTTP Request node while specifying the credential type through an expression. Because the pre-execution permission check compared the unresolved expression instead of the real credential type, the ownership check was skipped and the credential was loaded at execution time, letting the member use or exfiltrate a credential they were never granted. Exploitation required knowing the target credential's identifier. ## 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. ## Workarounds If upgrading is not immediately possible, administrators should consider the following temporary mitigations: - Restrict n8n instance access to fully trusted users only. - Exclude the HTTP Request node by adding `n8n-nodes-base.httpRequest` to the `NODES_EXCLUDE` environment variable, if the node is not required. - Audit credential sharing and workflow access to limit exposure of credential IDs to untrusted users. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
