NVD description
n8n versions before 1.123.67, 2.31.5, and 2.32.1 contain an arbitrary file write vulnerability in the Edit Image node, which passes its output format parameter to the underlying image library without validation. An authenticated user able to run workflows can supply a crafted format value to write arbitrary files outside the node's working directory on the n8n instance.
What to do
- Upgrade n8n to
1.123.67or later (or the patched release of your branch: 2.31.5). - Do not expose the component's API or UI to the internet without authentication in front of it.
