MEDIUM

Why flagged The PKGBUILD downloads a prebuilt AppImage binary from mixo.tech and executes it during the build phase (--appimage-extract extracts and then the entire squashfs-root is installed to /opt). The download host (mixo.tech) differs from the project's primary domain (mixo.dj), though both appear to be operated by the same Mixo company — mixo.tech is their CDN/download endpoint. The sha256sum is pinned, which mitigates tampering risk significantly. However, this is still a closed-source proprietary AppImage binary being executed and installed wholesale, sourced from a secondary domain. The risk is real but modest: if mixo.tech were compromised or is not actually controlled by the same entity as mixo.dj, arbitrary code would execute on the builder's machine. This fits the medium classification: an executed binary from a host that is not the canonical project domain, with no source code to audit.

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, …).
