MEDIUM

Why flagged The source is a tarball fetched from hub.darcs.net (a Darcs VCS hosting service), which is not an official distribution channel. The sha512sum is 'SKIP', meaning there is no integrity verification whatsoever. The downloaded artifact is compiled and the resulting binary is installed to /usr/bin. This is a real supply-chain concern: the host is not the upstream vendor's official release infrastructure, the checksum is skipped so any substitution would go undetected, and the artifact is compiled source code that gets executed. However, there is no evidence of active malice — darcs.net is a legitimate (if niche) VCS hosting platform, and the package appears to be a small cursor-positioning utility. The combination of non-standard host + SKIP checksum + compiled+installed binary warrants a MEDIUM rating.

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, …).
