MEDIUM

Why flagged The PKGBUILD downloads a file named 'popular-packages' (no extension) from a personal/commercial S3-compatible object store (DreamObjects) and installs it directly as an executable in /usr/bin. There is no upstream source repository, no version tag, no tarball — just a bare binary/script blob hosted on an unofficial third-party storage host. The sha256sum provides integrity against accidental corruption but not against a deliberate substitution by whoever controls that S3 bucket. Since the installed artifact is executed code (a shell script or binary placed in /usr/bin with mode 755), this is a genuine supply-chain concern: if the bucket is compromised or the maintainer replaces the file, users get arbitrary code execution with no way to audit the change. This matches the medium severity definition exactly: executed code from an unofficial/personal host.

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