This package has dated incident reports relevant to its trust history. Check the affected releases and the response before drawing conclusions about its current version.
append-only-vec has been quiet — last commit this week, but nothing suggests trouble: there are no open issues. This is a settled project, not a stalled one.

Why this verdict?
coasting — No commits for 90–365 days, with nothing else deteriorating.
Check a specific version for known advisories, documented mitigations and evidence-backed earlier-version options. Maintenance health is separate from vulnerability status.
Wiz reported that hijacked releases added a malicious dependency that ran during compilation. Rust responders removed those releases. Wiz also identified infrastructure shared with previously reported DPRK-linked campaigns.
A compromised maintainer account republished all three with a dependency on a look-alike proc-macro crate whose build script ran a payload at compile time, and yanked the older arrayref releases so Cargo would prefer the malicious one.
Deleted from crates.io within two hours, the yanked versions restored, the account locked.
