GHSA-725q-c4vp-q4cg: Duplicate Advisory: Race Condition in Git Clone Node Allows Authenticated Users to Achieve Remote Code Execution

n8n (a workflow automation platform) before versions 1.123.64, 2.29.8, and 2.30.1 had a race condition vulnerability (a timing flaw where an attacker can change something between when it's checked and when it's used) in its Git node that let authenticated users execute arbitrary code on the server by swapping a directory for a symlink after validation, allowing them to load malicious custom nodes when n8n restarts.
