LOW

Why flagged The source is a proprietary MSI installer from Yandex's official CDN, which is a plausible project-owned host despite not being on the standard whitelist; the package builds and installs the official client without executing untrusted remote code or introducing malicious payloads.

Triggered rules

LOW AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (qwen/qwen3-235b-a22b-07-25) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The source is a proprietary MSI installer from Yandex's official CDN, which is a plausible project-owned host despite not being on the standard whitelist; the package builds and installs the official client without executing untrusted remote code or introducing malicious payloads.

1 higher static finding superseded - not the current verdict (shown for transparency)

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, …).
