Why flagged

The package downloads a prebuilt binary from a non-public, obfuscated URL via a cookie-authenticated flow, which creates an unverifiable supply chain; if the Symless domain were compromised or the token endpoint subverted, an attacker could silently replace the binary without detection, constituting a medium-severity supply-chain risk.

Triggered rules

Medium External download from an untrusted host, not in source=() external_download_not_in_source

curl/wget fetches a URL on a non-allowlisted host that is not part of source=(), so it is not checksum-verified by makepkg.

PKGBUILD:34 curl -fsSL -o "${srcdir}/${_pkgfile}" "https://symless.com/synergy/api/download/${_pkgfile}?token=${token}"
