CVE-2026-65598
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedn8n before 1.123.64, 2.29.8, and 2.30.1 contains a TOCTOU race condition in the Git node's clone operation that allows authenticated users to bypass path restrictions by swapping a directory for a symlink after the path is validated but before the clone runs. This lets an attacker plant a crafted repository in the community node directory, which n8n loads as a custom node on the next restart, executing arbitrary JavaScript on the server. Both self-hosted and cloud instances are affected.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade to n8n version 1.123.64 (stable) or 2.30.1 (if on 2.x track), or version 2.29.8 as an alternative 2.x release
- Identify your current n8n version by checking the startup logs or running `n8n --version`
- For self-hosted installations using npm: run `npm install [email protected]` to upgrade to the 1.x stable release, or `npm install [email protected]` if you are on the 2.x track
- For Docker deployments: pull the new image with `docker pull n8nio/n8n:1.123.64` or `docker pull n8nio/n8n:2.30.1` and recreate your container
- For other deployment methods (binary, docker-compose, etc.): update your configuration to reference the fixed version number
- After upgrading, restart the n8n service to load the patched version
- Verify the upgrade was successful by checking the version again and reviewing the changelog for 1.123.64/2.29.8/2.30.1
