MEDIUM

Why flagged The PKGBUILD runs 'pip install --upgrade mangadex-downloader' inside the package() function, which downloads and executes arbitrary Python code from PyPI at build/install time without any version pinning or integrity verification. This is a genuine supply-chain concern: the --upgrade flag means whatever version PyPI serves at that moment is installed, bypassing pacman's dependency tracking and reproducibility guarantees. Additionally, the package installs a .so extension into /home/$USER/.local/share rather than a proper system path, and the sha512sum appears to have an incorrect length (127 hex chars instead of 128), suggesting a possible integrity issue. The pip install is the primary concern — it executes unverified, unpinned external code during packaging, which is a real medium-severity supply-chain risk.

Triggered rules

MEDIUM pip install of an external package pip_install_external

`pip install <package>` fetches an unpinned package from PyPI at build time, outside source=() and makepkg's checksums.
