MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary from zep.run, which is not the canonical GitHub releases host (github.com/XerWoho/zeP). The project URL points to GitHub but the actual binary is fetched from a separate domain (zep.run). This is a supply-chain concern: zep.run is a third-party domain not directly tied to the GitHub project in a verifiable way, and a prebuilt executable is installed directly to /usr/bin. The sha256sum provides some integrity protection, but does not protect against the domain owner substituting a malicious binary and updating the checksum in the PKGBUILD. This is a classic medium-severity pattern: executed binary from an unofficial/personal release host rather than the canonical upstream source host.
