  "details": "## Impact\n\nThe 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\u0027s working directory. An authenticated user able to run workflows could use this to write arbitrary files in the n8n instance.\n\n## Patches\n\nThe 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.\n\n## Workarounds\n\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Restrict n8n instance access to fully trusted users only.\n- Disable the Edit Image node by adding `n8n-nodes-base.editImage` to the `NODES_EXCLUDE` environment variable.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.",
