Why flagged

The source is a prebuilt source tarball hosted on Dropbox (a personal/cloud storage host), not the official upstream release server (onscripter.unclemion.com). Dropbox links can be silently replaced by the account owner at any time, and the URL is not a canonical upstream release mirror. The package compiles and executes the resulting binary, so a substituted archive could lead to arbitrary code execution at build time. The MD5 checksum provides weak integrity protection (MD5 is cryptographically broken). However, this is a well-known open-source project (ONScripter-EN), the version is old (2011), and the pattern of hosting source tarballs on Dropbox was common for small open-source projects of that era. There is no evidence of active malice, obfuscation, or exfiltration. This is a genuine but low-probability supply-chain risk: medium severity is appropriate.

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, …).
