LOW

Why flagged The package downloads a prebuilt .xpi extension from addons.mozilla.org, Mozilla's official add-on repository, which is a trusted source despite not being on the analyzer's whitelist; the .xpi is installed as-is without execution during build, and the host is not swappable by an unrelated third party.

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 .xpi extension from addons.mozilla.org, Mozilla's official add-on repository, which is a trusted source despite not being on the analyzer's whitelist; the .xpi is installed as-is without execution during build, and the host is not swappable by an unrelated third party.

1 higher static finding superseded - not the current verdict (shown for transparency)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