Why flagged

The package downloads a prebuilt .deb binary from rakudave.synology.me, which is a personal Synology NAS host rather than an official project release platform (GitHub releases, SourceForge, etc.). The binary is extracted and installed directly to /opt, then symlinked into /usr/bin — meaning arbitrary executable code from this personal host runs on the user's system. While a sha256sum is present (providing integrity against accidental corruption), it offers no protection if the host owner replaces the file with a new binary at the same URL. The project's official URL is rakudave.ch/jnetmap, and this Synology subdomain appears to be the maintainer's personal server acting as a download mirror, not a recognized release infrastructure. This is a genuine supply-chain concern: a prebuilt Java application binary from a non-standard personal host that gets executed directly. The risk is real but not clearly malicious, fitting the medium classification.

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, …).
