RUSTSEC-2025-0171: soundness issue

What to do

1. See which version you have: cargo tree -i mod3d-base (it also shows which of your dependencies pulls it in).
2. Update within your version requirement: cargo update -p mod3d-base. If the fix is a newer major or minor than your requirement allows, raise it in Cargo.toml (for example mod3d-base = "0.3.0") or update the dependency that pulls it in.
3. Check again with cargo audit, or paste your Cargo.lock into our Cargo.toml checker.
