Why flagged

This PKGBUILD downloads a prebuilt binary RPM from mirror.rosalab.ru (a ROSA Linux mirror, not the upstream project's official release channel at sourceforge.net) and installs the extracted binary directly. Two compounding issues: (1) the binary is a precompiled executable from a third-party Linux distribution's mirror, not the upstream source, meaning any compromise or tampering of that mirror would result in arbitrary code execution on the user's system; (2) sha256sums=('SKIP') means there is zero integrity verification — any content served at that URL is accepted unconditionally. The commented-out alternative section shows the maintainer knows the upstream SourceForge source exists but chose the ROSA mirror instead. This is a genuine supply-chain concern: an executed binary from a non-official, non-upstream host with no checksum validation.

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, …).
