How to Fix GHSA-cj9h-qx8g-pq2g

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-cj9h-qx8g-pq2g, 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 n8n's credential-access checks validated only a node's top-level credentials, not credentials referenced inside an Execute Sub-workflow node's inline workflow JSON. A member with editor access to a shared workflow could reference a credential they were not permitted to use inside that inline JSON; it passed both save-time and runtime validation and resolved in the parent workflow's project context, letting the member use or exfiltrate a credential they could not otherwise access. Exploitation requires workflow sharing to be enabled and the attacker to have been explicitly granted Editor access to a shared workflow. The attacker must also know the target credential's ID. ## 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 workflow sharing to fully trusted users only, and avoid granting Editor access to untrusted members on workflows that use sensitive credentials. - Audit shared workflows for Execute Sub-workflow nodes with Source = "Parameter" and review their inline workflow definitions for unexpected credential references. - Restrict network egress from the n8n instance to prevent connections to attacker-controlled endpoints. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
