Why flagged

The PKGBUILD downloads a prebuilt Windows PE executable (EVPlayer2_v4.8.2.exe) from ctpublic.ieway.cn, which appears to be the vendor's own CDN (ieway.cn is the official EV Tools/ieway company domain matching the url= field). The executable is extracted with innoextract and then run under Wine. Two concerns: (1) sha256sums=('SKIP') means no integrity verification — if the CDN is compromised or the file is swapped, users get arbitrary code executed under Wine with no detection; (2) the binary is a closed-source Windows executable run via Wine, which is an inherently elevated-trust operation. However, the host domain matches the official vendor URL, so this is not an obviously unofficial or personal host — it is the vendor's own distribution CDN. The SKIP checksum is the real issue here: it is sloppy and creates a supply-chain window, but the source itself appears legitimate. This sits at the lower end of medium: executed proprietary binary with no checksum, but from what appears to be the official vendor host.

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, …).
