LOW

Why flagged The package downloads a prebuilt Linux library and data files from a non-whitelisted host due to GitHub Actions access limitations, but the files are from the official project's release ecosystem and include verifiable checksums; the worst case of a swapped source is limited to code execution of the library, which is expected in AUR packages, but the context and checksums reduce risk.

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 Linux library and data files from a non-whitelisted host due to GitHub Actions access limitations, but the files are from the official project's release ecosystem and include verifiable checksums; the worst case of a swapped source is limited to code execution of the library, which is expected in AUR packages, but the context and checksums reduce risk.

1 higher static finding superseded - not the current verdict (shown for transparency)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

      17# Why do I have to host this artifact (original source: https://github.com/AmusementClub/vs-mlrt/actions/runs/19187416567)
    
      18# on a separate server? Because:
    
      19# - We can't build the library from source without using custom versions of onnx and shit.
    
      20# - The maintainers of vs-mlrt only publish Windows binaries to their release tags, not Linux ones.
    
      21# - Apparently Github does not let you download Actions artifacts without being logged in.
    
      22# The last one of those being particularly stupid. It's a public artifact but you can't download it without a Github account.
    
      23# ANY Github account, even if it's not associated with AmusementClub.
