MEDIUM

Why flagged The PKGBUILD downloads a prebuilt x86_64 binary tarball from a Cloudflare R2 bucket (pub-0ff293aefb644607ac910219d9762b50.r2.dev) which is a personal/vendor-controlled cloud storage bucket rather than an official distribution channel like GitHub releases or the vendor's own infrastructure. The binary is an Electron app (evidenced by the Chromium/Electron license files) that gets installed and executed directly. While sha256sums are provided (mitigating substitution attacks at build time), the source is not a recognized official release host — it's a Cloudflare R2 bucket that could be controlled by anyone. The official URL is hexcore.xyz but the binary comes from an R2 bucket with an opaque ID. This is a genuine medium-severity supply-chain concern: a prebuilt executable from a non-canonical host with no reproducibility guarantee, though the checksum does provide some protection against in-transit tampering. The risk is that the bucket owner could rotate the file at a new version bump without any source code audit trail.
