Summary

A new version of the `arrayref` crate was published with a direct dependency on `proc-macro1`, which would execute a malicious build script.

This compromised version was published on 2026-08-20 and removed approximately 86 minutes later. It was downloaded 2,285 times, which constituted less than 10% of `arrayref` download traffic across all versions, as most users had older versions of `arrayref` in their lockfiles.
