MEDIUM

Why flagged The PKGBUILD downloads a prebuilt .deb binary (containing executable code/scripts) from download.flexibee.eu, which is the official vendor download host for the ABRA FlexiBee accounting software. The host itself is legitimate and vendor-controlled, so this is not an unofficial or personal host. However, sha256sums='SKIP' means there is no integrity verification of the downloaded binary, creating a real supply-chain risk: if the download is intercepted (MITM — note the source URL uses HTTP, not HTTPS... actually it does use HTTPS), or if the vendor host is compromised, a malicious binary could be installed without detection. The URL does use HTTPS which mitigates MITM somewhat, but the complete absence of a checksum for an executed binary is a genuine medium-severity concern. The package extracts and installs binaries from the .deb directly. This is a real but not clearly malicious supply-chain concern — the vendor host is legitimate but the missing checksum for executable content warrants medium severity.

Triggered rules

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, …).

An AI model (anthropic/claude-4.6-sonnet-20260217) reviewed this and agrees it is MEDIUM (confidence 72%): The PKGBUILD downloads a prebuilt .deb binary (containing executable code/scripts) from download.flexibee.eu, which is the official vendor download host for the ABRA FlexiBee accounting software.
