Summary

Duplicate Advisory: Race Condition in Git Clone Node Allows Authenticated Users to Achieve Remote Code Execution

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-g3r5-9h93-4j2c. This link is maintained to preserve external references.

Original Description

n8n before 1.123.64, 2.29.8, and 2.30.1 contains a TOCTOU race condition in the Git node's clone operation that allows authenticated users to bypass path restrictions by swapping a directory for a symlink after the path is validated but before the clone runs. This lets an attacker plant a crafted repository in the community node directory, which n8n loads as a custom node on the next restart, executing arbitrary JavaScript on the server. Both self-hosted and cloud instances are affected.

Severity

8.9 (High)
