Why flagged

The package downloads a prebuilt RPM from an IBM API endpoint using a resolved redirect URL not listed in source=(), with a hardcoded checksum; while the source is plausibly official, the download mechanism is opaque and the binary artifact is not independently verifiable, creating a supply-chain risk if the API or host were compromised.

Triggered rules

Medium External download from an untrusted host, not in source=() external_download_not_in_source

curl/wget fetches a URL on a non-allowlisted host that is not part of source=(), so it is not checksum-verified by makepkg.
