MEDIUM

Why flagged This PKGBUILD downloads and installs a prebuilt proprietary binary .deb package from packages.memopal.com, which is the vendor's own package repository (not a personal or unofficial host). The sha512 checksums are present and pin the specific binary. However, the concern is real: this is a closed-source, prebuilt binary daemon being installed on the system, sourced from a vendor-controlled host that is not a widely-recognized distribution channel. If the vendor's package server were compromised or the vendor acted maliciously, the pinned checksum provides some protection against silent substitution, but the binary itself is opaque and executes with system privileges as a backup/sync daemon. This is a legitimate medium-severity supply-chain concern: executed proprietary binary from a non-standard host, not clearly malicious but not verifiable. The checksums do mitigate the substitution risk somewhat, making this closer to the lower end of medium rather than high.
