MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb package from apt.evostream.com, which is the official EvoStream vendor APT repository (not a personal or unofficial host). However, the package installs a closed-source, precompiled media server binary directly onto the system. The integrity check uses only MD5 (weak, but present). The main concern is that this is an executed binary from a vendor-controlled host with no strong integrity guarantee (no SHA256/SHA512, no GPG signature verification). If apt.evostream.com were compromised or the binary swapped, the MD5 check provides minimal protection. This is a legitimate supply-chain concern for a binary-only package from a non-Arch vendor repository, which justifies MEDIUM. It is not HIGH because the host is the official vendor's own APT repository, not a personal/random host, and there is no evidence of malicious intent.

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, …).
