View on AUR

Why flagged

The PKGBUILD downloads a prebuilt .deb binary directly from internxt.com (the official vendor's domain) and installs it. While internxt.com is the legitimate upstream vendor for Internxt's X Core product, the package installs an unverifiable prebuilt binary (Electron app based on dependencies) without any integrity verification beyond a single sha256sum of the .deb. The sha256sum pins a specific version, which is a positive signal, but the binary itself cannot be audited. The source URL uses a non-versioned path (/downloads/core.deb) which could silently serve a different binary if the checksum is ever updated carelessly. However, since this is the official vendor domain and the checksum is present, this is a standard 'binary repackage from official vendor' pattern common in AUR (like -bin packages for many commercial apps). The risk is real but typical for binary AUR packages: trust is delegated to the vendor. This is a genuine medium concern — executed binary from a vendor host with no source build — but not elevated to high since it is the official vendor domain with a checksum.

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, …).
