During `pip install` (or `pip wheel` / sdist build) pip resolves this direct-URL requirement into the build isolation environment and executes the tarball's setup.py, giving the URL owner arbitrary code execution on the installer's machine. The URL is unpinned (no hash), is not on the publisher's domain, and webhook.site content is fully attacker-controlled and mutable.
