LOW

Why flagged The .deb is downloaded from Slack's official CDN (downloads.slack-edge.com) with a b2sum checksum; the 'compressor' and patch files are local/bundled with no URL, so no unverifiable remote execution. The only mild concern is the bundled 'compressor' file whose purpose is unclear but has a checksum, and the package is new with few votes — overall low risk.

Triggered rules

LOW AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (anthropic/claude-sonnet-4.6) reviewed the full PKGBUILD and judged it LOW (confidence 70%): The .deb is downloaded from Slack's official CDN (downloads.slack-edge.com) with a b2sum checksum; the 'compressor' and patch files are local/bundled with no URL, so no unverifiable remote execution. The only mild concern is the bundled 'compressor' file whose purpose is unclear but has a checksum, and the package is new with few votes — overall low risk.

1 higher static finding superseded - not the current verdict (shown for transparency)

MEDIUM source=() URL on a non-standard host source_untrusted_domain
