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.
