Description
The Git node clone operation allows an authenticated workflow user to replace a validated directory with a symlink before the cloning process occurs. This allows the user to place a crafted repository into the community node directory, which is then loaded as a custom JavaScript node upon server restart, leading to arbitrary code execution on the server.
