RELIABLE

This image is acceptable for production, but remediating the identified vulnerabilities is recommended to reduce the attack surface. The image has 21 exposed findings, including 4 at severity 6.0 or higher, but none reach 7.0, and there are no post-exploit-only findings. The main practical concerns are denial-of-service conditions tied to OpenSSL, specifically CVE-2026-18798 and CVE-2026-14457. These only apply under non-default configurations: an OpenSSL QUIC server for CVE-2026-18798, or RFC7250 Raw Public Keys with only a private key and no certificate for CVE-2026-14457. If those features are not enabled, or if the RPK configuration includes a certificate, the associated risk is eliminated. No unauthorized access, data exposure, or remote code execution is indicated by the provided findings.
