MEDIUM

Why flagged The PKGBUILD downloads a prebuilt application archive (app.tar.xz) from a personal Vercel deployment (vue-slwyts.vercel.app) that is not the official project domain (platinum.flysoftbeta.cn). This is a personal/unofficial host with no verifiable connection to the upstream project's release infrastructure. The archive is extracted and its contents (the 'app' directory) are installed directly into /opt/platinum and executed via an Electron wrapper. While md5sums are present, MD5 is cryptographically weak and the hash itself could be updated alongside a malicious payload. The duplicate source= assignment (first line is overridden by the second) is sloppy but not itself a security issue. The core concern is a prebuilt binary blob from an unofficial personal hosting service being installed and executed — a genuine supply-chain risk warranting medium severity.
