MEDIUM

Why flagged The PKGBUILD downloads a prebuilt RPM from an IBM API endpoint not listed in source=(), using a dynamically resolved URL; while the host is plausibly official, the download is unverifiable and the checksum is only checked after retrieval, creating a supply-chain risk if the API 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.

PKGBUILD:55 curl -fsS -D - -o /dev/null -X POST 'https://bob.ibm.com/api/download/bobide' \
