MEDIUM

Why flagged The PKGBUILD downloads a prebuilt JAR (executable code) from Maven Central using curl inside package() rather than declaring it in source=() with a checksum. While Maven Central is a legitimate and well-known repository, bypassing makepkg's integrity verification (no sha256sums/b2sums) means there is no tamper detection — a compromised or MITM'd response would be silently installed. The JAR is executed at runtime by the JVM, so it constitutes executed code without integrity verification. This is a genuine, if moderate, supply-chain concern: not clearly malicious, but the missing checksum on an executed artifact from an external host warrants MEDIUM. Additionally, the 'install $startdir/$pkgname' line installs a file from the source tree that is not declared in source=() either, which is another unverified artifact.

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.
