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).
- Avoid cloning or interacting with untrusted repositories using the Git Node.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
