Remediation

The crate's build script fetches a prebuilt at compile time, outside the registry's checksums. Pin or vendor the download (the crate's own environment variable, a from-source feature) so the build takes nothing from the network.

Remediation

Inspect the writer and input chain. Confirm the object comes from a reviewed build step or declared prebuilt dependency. If its origin cannot be verified, replace it and rebuild.
