MEDIUM

Why flagged The PKGBUILD downloads prebuilt proprietary .deb binaries from edu-download.wpscdn.cn, which is the official WPS CDN domain used by Kingsoft for their Chinese education product (wpscdn.cn is the legitimate CDN for WPS Office in China, analogous to how wps.com is used internationally). SHA-256 checksums are provided for all three architectures. However, this is still a prebuilt closed-source binary from a CDN that is not independently verifiable as an official release channel in the same way a GitHub release or official package repository would be — there is no GPG signature verification, and the CDN could theoretically serve different content. The package also contains an obfuscated sed substitution ('fix xxx Njk0QkYtWVVEQkctRUFSNjktQlBSR0ItQVRRWEgK' with base64-encoded comment and opaque string replacement in oem.ini) which modifies what appears to be a license/activation key field, raising a mild concern about license circumvention, though it could also be a legitimate OEM configuration fix. The binary is executed code from a CDN without GPG verification, which is a genuine medium-level supply-chain concern, but the domain is the legitimate Kingsoft CDN and checksums are present. The oem.ini modification is suspicious but not clearly piracy.
