Why flagged

The PKGBUILD downloads a prebuilt binary archive (a compiled Java PSP emulator with native libraries) from files.emunewz.net, which is a third-party build host rather than the official jpcsp.org or a recognized mirror. The archive is extracted and installed directly under /opt. While emunewz.net appears to be a known emulator build hosting site that has historically hosted JPCSP nightly builds, it is not the canonical upstream source and is not under the project maintainers' direct control. A compromise of that host would result in arbitrary code execution on the user's machine. The MD5 checksum provides minimal integrity protection (MD5 is cryptographically broken). This is a genuine supply-chain concern: executed binary from a non-official third-party host. Not clearly malicious, but the risk is real and warrants medium severity.

Triggered rules

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
