Why flagged

The package downloads a prebuilt binary ZIP archive (NemerleBinaries-net-4.0-v1.2.507.0.zip) from nemerle.org, which is the official project website for the Nemerle language. This is not a personal or unofficial host — it is the canonical upstream distribution point. However, the concern is real in a supply-chain sense: the download is a prebuilt binary bundle (compiled .NET assemblies/executables) rather than source code, and the integrity check is only an MD5 sum (weak, collision-prone). The binaries are installed to /opt/nemerle and executed via wrapper scripts. If nemerle.org were compromised or the specific nightly build URL were tampered with, arbitrary .NET code would execute on the user's system. The nightly/build-numbered URL path also means this is not a stable release artifact. This is a genuine medium-severity supply-chain concern: prebuilt binaries from an upstream host with only MD5 verification, not a false positive, but also not clearly malicious.

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, …).
