Sources and claim methodology

Upstream source description

n8n is an open source workflow automation platform. Prior to 1.123.64, 2.29.8, and 2.30.1, the Git node clone operation allows an authenticated workflow user to swap a validated directory for a symlink before cloning, planting a crafted repository in the community node directory that loads as a custom JavaScript node after restart and executes arbitrary code on the server. This issue is fixed in versions 1.123.64, 2.29.8, and 2.30.1.
