n8n: Authenticated code execution in the n8n Git node
Authenticated n8n users with rights to create and execute workflows could achieve code execution on the n8n host. Using the Git node, under the default git security settings, by staging a crafted local repository, an attacker could cause git to run hooks, executing arbitrary commands as the n8n process user.
Both self-hosted and cloud instances are affected where authenticated users can create and execute workflows using the Git node.
The issue has been fixed in n8n versions 1.123.67, 2.31.5, and 2.32.1. Users should upgrade to one of these versions or later to remediate the vulnerability.
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
n8n-nodes-base.git to the NODES_EXCLUDE environment variable.These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
