MEDIUM

Why flagged The PKGBUILD downloads a prebuilt executable script (streamcz-dl-3) from a personal/unofficial host (xpisar.wz.cz) and installs it directly into /usr/bin with execute permissions. There is no checksum beyond a single MD5 (which is cryptographically weak and trivially collisible), no GPG signature, and no source code to audit. The host is a personal wz.cz free-hosting subdomain, not an official upstream release infrastructure. If the host is compromised or the file is substituted, an arbitrary bash script would be executed as root during installation. This is a genuine supply-chain concern: an executed script from an unofficial personal host with only MD5 verification. The cheaper model's MEDIUM rating is correct.

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, …).
