MEDIUM

Why flagged This PKGBUILD downloads a prebuilt, closed-source proprietary binary from releases.omnara.com (a project-specific but non-standard host) and installs it as an executable at /usr/bin/omnara, also setting it up as a persistent systemd user service that runs on login. The binary is not from a well-known, auditable source (e.g., GitHub releases with provenance), and the host could be compromised or repurposed. The binary runs as a daemon with network access ('After=network.target'), controls AI coding agents, and logs to the user's home directory. There is a sha256sum provided, which mitigates tampering in transit but does not address the trustworthiness of the upstream host or the binary itself. This is a genuine medium-severity supply-chain concern: an opaque binary from a personal/project-specific release host installed system-wide and run persistently as a service.

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, …).
