- Product
- n8n
- CVE
- CVE-2026-65598
- Affected
- npm/n8n < 1.123.64, >= 2.0.0-rc.0 < 2.29.8, >= 2.30.0 < 2.30.1
- Fixed in
- 1.123.64
Last verified against sources: October 26, 2026
Am I affected?
n8n: affected npm/n8n < 1.123.64, >= 2.0.0-rc.0 < 2.29.8, >= 2.30.0 < 2.30.1. Fixed in 1.123.64.
- Check your version: run
npm ls n8n. Versions < 1.123.64 of n8n are affected. [1]
What to do now
- Upgrade to the fixed version: run
npm install n8n@1.123.64(first patched version 1.123.64). [1] - Upgrade to the patched version once available to remediate the vulnerability. [1]
- Restrict n8n instance access to fully trusted users only. [1]
- Disable the Git node by adding
n8n-nodes-base.gitto theNODES_EXCLUDEenvironment variable. [1] - Restrict network egress from the n8n instance to prevent connections to attacker-controlled git repositories. [1]
General practice, not from the source: if the affected software could read tokens or credentials, rotate them after upgrading; pin versions and review changes before updating tools your agents run.
What happened
- A TOCTOU race condition in the Git node's clone operation lets an authenticated user bypass its path restrictions by swapping a directory for a symlink after the path is validated but before the clone runs. [1]
- This plants a crafted repository in the community node directory, which n8n loads as a custom node on the next restart. [1]
- Since nodes execute JavaScript, this yields arbitrary code execution on the server. [1]
