MEDIUM

Why flagged Installs a prebuilt x86_64 binary (avrasm2) downloaded from a Microchip forum file-hosting URL rather than an official release infrastructure endpoint; while Microchip is the legitimate vendor, the download is a forum attachment/document servlet that could be swapped without notice, and the binary is installed executable without any verification beyond 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, …).
