MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb package from apt.evostream.com, which is the vendor's own Debian APT repository — a plausible official source for EvoStream software. However, it uses only an MD5 checksum (cryptographically weak, collision-prone) for integrity verification, and the host is not a well-known, widely-audited distribution channel. The package installs pre-compiled web service binaries/files directly from this .deb without any signature verification (no GPG/PGP check). If the host were compromised or the file silently replaced, the weak MD5 check would not reliably detect substitution. This is a genuine supply-chain concern: executed/installed code from a vendor-controlled but externally-hosted binary artifact with insufficient integrity guarantees. Not clearly malicious, but a real medium-severity packaging risk.

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
