Why flagged

This PKGBUILD downloads a prebuilt binary Snap package from download.xvisiotech.com (a vendor-specific host, not a standard distribution channel like snapcraft.io) and executes it via 'snap install --devmode'. The --devmode flag disables Snap's confinement/sandboxing entirely, meaning the installed snap runs with full system access. The binary is verified only by a weak MD5 checksum (not SHA256 or a cryptographic signature). While xvisiotech.com appears to be the legitimate vendor for SeerSense/Xvisio SLAM cameras, the combination of: (1) an unverifiable prebuilt binary from a non-standard host, (2) no sandboxing due to --devmode, and (3) only MD5 integrity checking constitutes a genuine supply-chain risk. If the host is compromised or the binary is substituted, arbitrary code executes with full system privileges. This is a real medium-severity concern, not a false positive.

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, …).
