LOW

Why flagged The snap file is downloaded from the official Snapcraft API (api.snapcraft.io) with a specific snap ID and revision, and has a sha512 checksum provided (not SKIP). The checksum is present and non-trivial, so integrity is verified. The source host is Canonical's official Snapcraft distribution infrastructure, not a personal or unofficial host. Extracting and repackaging snaps is a common AUR pattern for proprietary apps. The 'no-sandbox.sh' wrapper script also has a checksum. The main concern is that snap revisions can theoretically be updated server-side, but the specific revision is pinned and the checksum guards against substitution. The license is listed as 'unknown' which is sloppy but not a security issue. Overall this is a legitimate, if non-standard, packaging approach with no real supply-chain concern beyond the inherent trust in Canonical's Snapcraft infrastructure.

Triggered rules

LOW AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (anthropic/claude-4.6-sonnet-20260217) reviewed the full PKGBUILD and judged it LOW (confidence 75%): The snap file is downloaded from the official Snapcraft API (api.snapcraft.io) with a specific snap ID and revision, and has a sha512 checksum provided (not SKIP).

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
