Summary
n8n: Edit Image Node Format Injection Allows Arbitrary File Write
Details

Impact

The n8n Edit Image node passed its output format to the underlying image library without validation, so a crafted value could write bytes to a location outside the node's working directory. An authenticated user able to run workflows could use this to write arbitrary files in the n8n instance.

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.
  • Disable the Edit Image node by adding n8n-nodes-base.editImage to the NODES_EXCLUDE environment variable.

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