MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary zip from mapbox.s3.amazonaws.com (Mapbox's own S3 bucket) and installs it directly into /opt without any compilation. This is a legitimate Mapbox-owned distribution channel for their Mapbox Studio Classic desktop app (an Electron/Atom-shell application), so it is not an unofficial or personal host. However, installing a prebuilt binary blob from any external host — even a plausible vendor-owned one — is a genuine supply-chain concern: S3 bucket contents can be replaced, and there is no GPG signature verification, only a sha1sum (which protects against accidental corruption but not a targeted substitution if the bucket were compromised). The package is also quite old (v0.3.4, Mapbox Studio Classic was deprecated years ago), and the sha1sum algorithm is weak by modern standards. The risk is real but not elevated beyond a typical 'binary blob from vendor CDN' scenario, which is standard medium territory.

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, …).
