MEDIUM

Why flagged The PKGBUILD downloads a prebuilt binary from a legitimate GitHub releases URL (azimjohn/jprq, a real open-source project). There is no obfuscation, no encoded payload, no exfiltration, and no active source substitution. However, there are genuine concerns: (1) no checksums/integrity verification (no sha256sums, no source= array with hashes), meaning a compromised release asset or MITM could deliver a malicious binary undetected; (2) the binary is downloaded at build time rather than declared in the source array, bypassing makepkg's integrity checking entirely; (3) the case statement has duplicate 'Darwin $CARCH' entries and the architecture matching is broken (CARCH is an Arch Linux variable, not an architecture string like 'x86_64', so the Linux cases will never match correctly). These are real packaging quality and security concerns but not an active attack — the source is a known public GitHub project with a legitimate release. This rates as medium risk due to the missing integrity verification of an executed binary, not high.

Triggered rules

MEDIUM AI review downgraded a static finding llm_review

The static rules flagged this HIGH, but an AI model (anthropic/claude-4.6-sonnet-20260217) reviewed the full PKGBUILD and judged it MEDIUM (confidence 85%): The PKGBUILD downloads a prebuilt binary from a legitimate GitHub releases URL (azimjohn/jprq, a real open-source project). There is no obfuscation, no encoded payload, no exfiltration, and no active source substitution. However, there are genuine concerns: (1) no checksums/integrity verification (no sha256sums, no source= array with hashes), meaning a compromised release asset or MITM could deliver a malicious binary undetected; (2) the binary is downloaded at build time rather than declared in the source array, bypassing makepkg's integrity checking entirely; (3) the case statement has duplicate 'Darwin $CARCH' entries and the architecture matching is broken (CARCH is an Arch Linux variable, not an architecture string like 'x86_64', so the Linux cases will never match correctly). These are real packaging quality and security concerns but not an active attack — the source is a known public GitHub project with a legitimate release. This rates as medium risk due to the missing integrity verification of an executed binary, not high.

1 higher static finding superseded - not the current verdict (shown for transparency)

HIGH Downloaded file is executed download_then_exec

A file fetched with curl/wget (not part of source=(), so never checksum-verified) is later made executable or run — a fetch-and-execute pattern split across statements.
