Executive Summary

NEEDS_ATTENTION

This image is acceptable for production, but remediating the identified vulnerabilities is recommended to reduce the attack surface. The primary risk is CVE-2026-45416 in the Netty TLS handler, which allows a remote attacker to cause denial of service by sending a large ClientHello, leading to memory exhaustion and potential crash. This vulnerability affects the default configuration and is directly reachable by any TCP client. Upgrading Netty to version 4.1.135.Final or later fully resolves the issue. All other vulnerabilities are low severity and unlikely to be exploited in isolation, but updating the image when available is prudent.
