## Impact

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.

## Patches

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.

## Workarounds

If upgrading is not immediately possible, administrators should consider the following temporary mitigations: - Restrict n8n instance access to fully trusted users only. - Disable the Git node by adding `n8n-nodes-base.git` to the `NODES_EXCLUDE` environment variable. - Restrict network egress from the n8n instance to limit the impact of arbitrary code execution.

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
