Why flagged

The source tarball is fetched from orruba.org via a PHP document-management endpoint (?mdocs-file=1159) rather than the official ORNL FTP server (ftp.phy.ornl.gov, which is commented out). ORRUBA (Oak Ridge Rutgers University Barrel Array) is a legitimate nuclear physics collaboration that uses UPAK, so the host is plausibly project-affiliated rather than a random personal server. However, the distribution point is still unofficial/non-canonical, the URL is opaque (a numeric file ID rather than a named artifact), and the package compiles and installs Fortran/C binaries directly into the system. The md5sum provides only weak integrity assurance. The commented-out official ORNL source suggests the maintainer switched away from the canonical host, which is a mild supply-chain concern. The build also executes installed binaries (./txx, ./txxps) during the package() phase to generate documentation, meaning any compromise of the tarball could lead to code execution at build time. Overall this is a genuine medium-risk pattern: executed compiled code from a non-canonical host with weak integrity checking, but not clearly malicious.

Triggered rules

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
