MEDIUM

Why flagged The PKGBUILD downloads a prebuilt .deb binary from static.frdic.com, which is the official CDN/distribution host for Eudic (欧路词典) software products — frdic.com is the domain associated with the Eudic/Eusoft company that makes this Chinese dictionary/language learning software. This is not a random personal host; it is the vendor's own distribution infrastructure. However, the URL is not versioned (it fetches 'ting_en.deb' without a version in the path), meaning the sha256sum provides integrity protection only for the specific version captured at PKGBUILD creation time — future updates to the remote file would break the checksum. The sha256sum is present and pinned, which mitigates substitution risk. The package installs app.asar (Electron application code) and native unpacked resources from this binary, which is executed code from a non-open-source vendor host. This is a standard pattern for proprietary Electron app AUR packages (-bin suffix), and the risk profile is consistent with other similar AUR packages (e.g., eudic, baidunetdisk-bin). The concern is real but typical for this class of package: a medium supply-chain risk due to executed proprietary binary from a vendor CDN without source verification, but not elevated beyond that.
