MEDIUM

Why flagged The package downloads a prebuilt binary RPM from downloads.tandem.chat (the official vendor domain) and installs it directly. The use of sha512sums='SKIP' means there is no integrity verification — if the vendor's download endpoint were compromised or silently updated, users would receive and execute arbitrary code with no checksum protection. This is a real supply-chain concern: it's an executed binary from an external host with no pinned hash. However, the host is the official vendor domain (not a personal/unofficial host), which reduces but does not eliminate the risk. The SKIP checksum is the primary concern here, making this a legitimate medium-severity finding rather than a false positive.

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, …).
