Description
repomix contains a server-side request forgery vulnerability in the POST /api/pack endpoint that allows unauthenticated attackers to make arbitrary outbound requests. The endpoint fails to properly validate http://, https://, and file:// URLs before passing them to git clone, enabling attackers to access private network addresses, GCP metadata services, or local filesystem paths.
