LOW

Why flagged The PKGBUILD downloads a prebuilt JAR-based zip from bubblesoftapps.com, which is the official vendor website (same domain as the package URL). The use of `date +%F-%H` in the filename makes the checksum effectively non-reproducible (the filename changes hourly, so the sha256sum listed will rarely match a fresh download), but the checksum for the zip IS present in sha256sums — it just won't match after the timestamp rolls over. This is a sloppy/broken pattern rather than a security attack: the maintainer clearly intended to pin a specific build but the timestamped filename defeats that. The host is the legitimate vendor site, not a personal or unofficial mirror. The JARs are closed-source proprietary software (custom EULA), which is normal for AUR. No obfuscation, no exfiltration, no unofficial host. The main concern is the non-reproducible checksum due to the date-based filename, which is a quality/integrity issue but not an active supply-chain attack. Severity is low (sloppy, not dangerous).

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 72%): The PKGBUILD downloads a prebuilt JAR-based zip from bubblesoftapps.com, which is the official vendor website (same domain as the package URL). The use of `date +%F-%H` in the filename makes the checksum effectively non-reproducible (the filename changes hourly, so the sha256sum listed will rarely match a fresh download), but the checksum for the zip IS present in sha256sums — it just won't match after the timestamp rolls over.

1 higher static finding superseded - not the current verdict (shown for transparency)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