LOW

Why flagged The package downloads a prebuilt .deb from the official PicoTech labs domain, which is plausibly the project's own release infrastructure; unpacks it to extract the library and license; and installs a renamed postinst script for later use, with no evidence of remote code execution or obfuscation.

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 prebuilt .deb from the official PicoTech labs domain, which is plausibly the project's own release infrastructure; unpacks it to extract the library and license; and installs a renamed postinst script for later use, with no evidence of remote code execution or obfuscation.

1 higher static finding superseded - not the current verdict (shown for transparency)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