Description

Impact

A vulnerability in the Merge node's SQL Query mode allowed authenticated users with permission to create or modify workflows to write arbitrary files to the n8n server's filesystem potentially leading to remote code execution.

Patches

The issue has been fixed in n8n version 2.4.0, 1.118.0. Users should upgrade to this version 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.
  • Disable or restrict use of the Merge node if not essential for operations.
  • Review workflows for suspicious use of the Merge node's SQL Query mode.

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
