Description: The Python build tools depend on three packages — pygments, mkdocs, and pymdown-extensions — that are listed without pinned version numbers or cryptographic hash verification. When the build environment installs these dependencies using pip without version constraints, it resolves to the latest available version from PyPI at install time. This creates a window for supply chain attacks: a threat actor who compromises a package maintainer account, performs a typosquatting attack, or executes a dependency confusion attack can publish a malicious package version. The next build environment setup will install the malicious version, executing attacker-controlled code during package installation (via setup.py or pyproject.toml hooks) or at import time, with the full privileges of the build process.
