LOW

View on AUR

Why flagged

The package downloads a source archive and a certificate from the vendor's official domain (download.cyberghostvpn.com), which is plausibly project-owned; building from this source is normal AUR packaging, and the certificate download is from a known CA; no malicious or unverifiable executable payloads are present.

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 package downloads a source archive and a certificate from the vendor's official domain (download.cyberghostvpn.com), which is plausibly project-owned; building from this source is normal AUR packaging, and the certificate download is from a known CA; no malicious or unverifiable executable payloads are present.

1 higher static finding superseded - not the current verdict (shown for transparency)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