Self-hosted n8n has Legacy Code node that enables arbitrary file read/write
Collected exploitation and prediction evidence
Risk source coverageCISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.
No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Publishedn8n is an open source workflow automation platform. Prior to version 2.0.0, in self-hosted n8n instances where the Code node runs in legacy (non-task-runner) JavaScript execution mode, authenticated users with workflow editing access can invoke internal helper functions from within the Code node. This allows a workflow editor to perform actions on the n8n host with the same privileges as the n8n process, including: reading files from the host filesystem (subject to any file-access restrictions configured on the instance and OS/container permissions), and writing files to the host filesystem (subject to the same restrictions). This issue has been patched in version 2.0.0. Workarounds for this issue involve limiting file operations by setting N8N_RESTRICT_FILE_ACCESS_TO to a dedicated directory (e.g., ~/.n8n-files) and ensure it contains no sensitive data, keeping N8N_BLOCK_FILE_ACCESS_TO_N8N_FILES=true (default) to block access to .n8n and user-defined config files, and disabling high-risk nodes (including the Code node) using NODES_EXCLUDE if workflow editors are not fully trusted.

Published### Impact In self-hosted n8n instances where the Code node runs in legacy (non-task-runner) JavaScript execution mode, authenticated users with workflow editing access can invoke internal helper functions from within the Code node. This allows a workflow editor to perform actions on the n8n host with the same privileges as the n8n process, including: - Reading files from the host filesystem (subject to any file-access restrictions configured on the instance and OS/container permissions) - Writing files to the host filesystem (subject to the same restrictions) Starting with n8n version 1.2.1, access to files in the n8n home directory (`.n8n`) is blocked by default. However, this does not restrict access to other parts of the filesystem unless additional file access limitations are configured. ### Patches - Upgrade to **n8n version 2.0.0 or later**, where task runners are enabled by default for Code node execution. - On **n8n version 1.71.0 and above**, enable task runners by setting `N8N_RUNNERS_ENABLED=true`. ### Workarounds If you cannot immediately migrate to task runners: - Limit file operations by setting `N8N_RESTRICT_FILE_ACCESS_TO` to a dedicated directory (e.g., `~/.n8n-files`) and ensure it contains no sensitive data. - Keep `N8N_BLOCK_FILE_ACCESS_TO_N8N_FILES=true` (default) to block access to `.n8n` and user-defined config files. - If workflow editors are not fully trusted, consider disabling high-risk nodes (including the Code node) using `NODES_EXCLUDE`. ### Resources - n8n Docs: [Task runners](https://docs.n8n.io/hosting/configuration/task-runners/) - n8n Docs: [Task runner environment variables](https://docs.n8n.io/hosting/configuration/environment-variables/task-runners/) - n8n Docs: [Security environment variables](https://docs.n8n.io/hosting/configuration/environment-variables/security/#security-environment-variables) - n8n Docs: [v2.0 breaking changes](https://docs.n8n.io/2-0-breaking-changes/#enable-task-runners-by-default)
