Today, we released Quarkus 3.27.5.1, an emergency release for the 3.27 LTS stream. This release fixes the following CVE: CVE-2026-16308 - Quarkus REST denial of service via unbounded multipart MIME part-header accumulation It also fixes a native image regression introduced by the Netty upgrade in 3.27.5 and upgrades the PostgreSQL JDBC driver to 42.7.13.
