MEDIUM

Why flagged Two real concerns here: (1) A prebuilt binary archive is downloaded from download-chromium.appspot.com with sha256sums=('SKIP'), meaning no integrity verification. While download-chromium.appspot.com is a Google-operated service that serves Chromium snapshots, the lack of checksum means any MITM or server-side substitution would go undetected. (2) The package hardcodes real Google API credentials (GOOGLE_API_KEY, GOOGLE_DEFAULT_CLIENT_ID, GOOGLE_DEFAULT_CLIENT_SECRET) in a world-readable shell script — these are the well-known public Chromium build keys, not a secret exfiltration, but worth noting. The primary concern remains the SKIP'd checksum on an executed binary: even from a legitimate host, this is a genuine supply-chain risk since the binary is executed directly on the user's system. The host itself (appspot.com/Google) is semi-official for Chromium snapshots, which keeps this from being high severity, but the missing integrity check on an executed binary warrants medium.

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, …).
