MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary .deb from cache.getlazarus.org (the vendor's own CDN/cache subdomain, not a random personal host, but still not a primary official distribution channel like GitHub releases or a distro mirror). More critically, the checksum is 'SKIP', meaning there is zero integrity verification on the downloaded executable. The package extracts and installs a binary directly into the system path. While getlazarus.org appears to be the legitimate upstream vendor for Lazarus IDE-related tools, the combination of: (1) a prebuilt binary from a cache/CDN subdomain rather than a canonical release URL, and (2) no checksum verification whatsoever, creates a genuine supply-chain risk — if the host is compromised or the file is substituted, users would install arbitrary code with no detection. This is a textbook medium-severity concern: not clearly malicious, but a real code-execution risk from an unverified binary source.
