LOW

Why flagged The source is pulled directly from the official upstream GitHub repository (openmsr/CAD_to_OpenMC) via git+https, which is the canonical location for this project. The SKIP checksum is normal for VCS sources. The main concern flagged is 'pip install --break-system-packages -r requirements.txt' inside the package() function. This is sloppy packaging practice: it installs dependencies outside pacman's control and writes to the live system rather than $pkgdir, but the requirements.txt comes from the same upstream git repository already cloned, so there is no separate untrusted fetch of unknown content. The pip invocation is a packaging quality issue (dependencies should be declared in depends/makedepends and installed properly), not a supply-chain attack vector introducing external untrusted binaries. The severity is low rather than medium because the executed code originates from the same official upstream source already fetched, not from a separate unofficial or personal host.

Triggered rules

LOW 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. Severity reduced: python-* packages routinely use pip.

PKGBUILD:51 pip install --break-system-packages -r requirements.txt
