n8n vulnerable to Remote Code Execution via Git Node Custom Pre-Commit Hook

Impact

The n8n Git node allows workflows to set arbitrary Git configuration values through the _Add Config_ operation. When an attacker-controlled workflow sets core.hooksPath to a directory within the cloned repository containing a Git hook such as pre-commit, Git executes that hook during subsequent Git operations. Because Git hooks run as local system commands, this behavior can lead to arbitrary command execution on the underlying n8n host.

Successful exploitation requires the ability to create or modify an n8n workflow that uses the Git node.

Affected versions: ≥ 0.123.1 and < 1.119.2

Patches

This issue has been patched in n8n version 1.119.2.

All users running affected versions should upgrade to 1.119.2 or later.

Workarounds

If upgrading is not immediately possible, the following mitigations can reduce exposure:

• Exclude the Git node ([Docs](https://n8n-docs.teamlab.info/hosting/securing/blocking-nodes/#exclude-nodes)).
• Avoid cloning or interacting with untrusted repositories using the Git Node.
