    Issue
    A new version of the `append-only-vec` crate was published with a direct dependency on `proc-macro1`, which would execute a malicious build script. The compromised version of this crate was published on 2026-08-20, and was removed approximately 107 minutes later. The compromised crate version was used as part of a malware campaign targeted at users of `arrayref`, which was downloaded 2,285 times before being removed; see [the `arrayref` advisory][arrayref-advisory] for more detail.
