How to Fix CVE-2026-25049

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: 1.123.17 
npm install n8n@1.123.17
n8n fixed: 2.5.2 
npm install n8n@2.5.2
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 CVE-2026-25049, 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 1.123.17), 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-913: Improper Control of Dynamically-Managed Code Resources, where the product does not properly restrict reading from or writing to dynamically-managed code resources such as variables, objects, classes, attributes, functions, or executable instructions or statements. 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 Additional exploits in the expression evaluation of n8n have been identified and patched following [CVE-2025-68613](https://github.com/n8n-io/n8n/security/advisories/GHSA-v98v-ff95-f3cp). An authenticated user with permission to create or modify workflows could abuse crafted expressions in workflow parameters to trigger unintended system command execution on the host running n8n. ### Patches The issue has been fixed in n8n versions 1.123.17 and 2.5.2. 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: - Limit workflow creation and editing permissions to fully trusted users only. - Deploy n8n in a hardened environment with restricted operating system privileges and network access to reduce the impact of potential exploitation. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures. ### Resources - Best practices for [securing n8n](https://docs.n8n.io/hosting/securing/overview/) - Initial vulnerability advisory: [CVE-2025-68613](https://github.com/n8n-io/n8n/security/advisories/GHSA-v98v-ff95-f3cp) --- n8n has adopted CVSS 4.0 as primary score for all security advisories. CVSS 3.1 vector strings are provided for backward compatibility. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
