MEDIUM

Why flagged Installs a prebuilt binary (Electron app tarball) downloaded from api.fluxer.app, which is the project's own API endpoint but is a non-standard download host for a low-vote, recently uploaded package; checksums are present and pinned, reducing but not eliminating the risk of a swappable prebuilt executable.

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, …).
