Why flagged

The package downloads a prebuilt AppImage from a plausible project-owned host (infomaniak.com, a known Swiss hosting provider), which is normal for AppImage packaging; the AppImage is extracted and repackaged without executing arbitrary remote code, and the worst case of a swapped source is running a malicious binary, but the source host is associated with the software vendor.

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-2507) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The package downloads a prebuilt AppImage from a plausible project-owned host (infomaniak.com, a known Swiss hosting provider), which is normal for AppImage packaging; the AppImage is extracted and repackaged without executing arbitrary remote code, and the worst case of a swapped source is running a malicious binary, but the source host is associated with the software vendor.

1 higher static finding superseded - not the current verdict (shown for transparency)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