- public hardening shipped in actions/download-artifact v8.0.0 on 2026-02-26: the action no longer attempts to unzip every downloaded file and checks Content-Type before extraction via PR #460. v8.0.1 on 2026-03-11 added a regression test for artifact name + content-type mismatches via PR #472. attribution linkage is inferred from topic and timing; no GHSA/CVE was published.
