MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary tarball directly from meocloud.pt (the official MEO Cloud vendor domain, operated by Altice/PT) and installs it system-wide by copying opt/ and usr/ trees. While meocloud.pt is the legitimate vendor's own domain (not a personal or third-party host), the package installs an opaque prebuilt binary with no source build, meaning the sha256sum is the only integrity guarantee. The binary is executed code installed into /opt and /usr, so if the upstream host were compromised or the binary swapped, the checksum would be the only line of defense. This is a classic 'binary blob from vendor' pattern — not clearly malicious, but a genuine supply-chain concern because there is no reproducible build and the binary runs with user privileges. Severity remains medium: it is the official vendor host, but the pattern of installing unverified prebuilt binaries without GPG signature verification is a real (if common) supply-chain risk.

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