MEDIUM
View on AUR ↗
Why flagged
The package downloads a prebuilt binary from a non-standard, non-whitelisted host (fluxdown.zerx.dev) which could be silently swapped, posing a supply-chain risk despite otherwise legitimate packaging.
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, …).
