n8n Has Expression Escape Vulnerability Leading to RCE

n8n

CVE-2026-25049 · Published Feb 4, 2026

Critical
Fix: upgrade to 1.123.17 or later (2 fixed versions below)
GitHub advisory

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.
