quartz-messenger
The PKGBUILD downloads a source tarball from a personal/unofficial GitLab-like instance (bultek.synchron.com.ua) using curl with -k (SSL verification disabled), bypassing the source=() array and thus all checksum verification. The commented-out source= line with md5sums='SKIP' shows the maintainer was aware of the proper mechanism but chose to use curl instead. The -k flag disabling TLS certificate verification makes this susceptible to MITM attacks in addition to the supply-chain risk from an unofficial host. The downloaded tarball is then compiled with cargo and the resulting binary is installed to /usr/bin. This is a genuine medium-severity supply-chain concern: executed/compiled code from an unofficial host with no integrity verification and TLS disabled.
Triggered rules
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.
