MEDIUM

Why flagged The PKGBUILD downloads a prebuilt self-extracting binary installer (et260b.x86_full.zip containing et260b.x86_keygen_V03.run) from filebase.trackbase.net, which is an unofficial third-party mirror rather than the official Splash Damage/id Software distribution channel. The .run file is then chmod +x'd and executed during the build phase (./et260b.x86_keygen_V03.run --noexec --nox11 --target). Executing a prebuilt binary from a non-official host is a genuine supply-chain concern: if the host were compromised or the file substituted, arbitrary code would run on the builder's machine. The md5sums provide weak integrity verification (MD5 is broken for collision resistance). However, trackbase.net is a well-known, long-standing Wolfenstein: Enemy Territory community mirror that has hosted this exact installer for many years, and the game itself is a free standalone release. This is a classic AUR pattern for old free-to-play games where the official download servers are gone. The risk is real but contextually low-probability. Medium severity is appropriate.

MEDIUM AI review of an ambiguous pattern llm_review

The static rules found a suspicious pattern they could not resolve, so an AI model (anthropic/claude-4.6-sonnet-20260217) reviewed it and judged it MEDIUM (confidence 72%): The PKGBUILD downloads a prebuilt self-extracting binary installer (et260b.x86_full.zip containing et260b.x86_keygen_V03.run) from filebase.trackbase.net, which is an unofficial third-party mirror rather than the official Splash Damage/id Software distribution channel.
