MEDIUM

Why flagged

The package downloads a prebuilt .deb from a Webex-hosted domain, which is not on the standard whitelist; while the host is plausibly official, the unverifiable binary payload presents a supply-chain risk if the source were compromised or silently swapped, warranting medium severity.

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, …).
