Why flagged

The PKGBUILD downloads a prebuilt binary .deb from deb-multimedia.org (a third-party Debian repository, not the upstream project's official release host) and installs its contents directly. Both checksums are 'SKIP', meaning there is zero integrity verification. deb-multimedia.org is a known but unofficial third-party repo; it is not the upstream qmc2 project's own release infrastructure. Executing arbitrary prebuilt binaries from a non-official host with no checksum verification is a genuine supply-chain risk — if the file is swapped or compromised, the user gets silent RCE. This matches the medium severity definition exactly: an executed binary from an unofficial/personal host.

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, …).
