This image is acceptable for production, but remediating the identified vulnerabilities is recommended to reduce the attack surface. It reports 29 exposed vulnerabilities, with only 2 at severity 6.0 or higher, no exposed finding above 6.0, and no post-exploit-only findings. The main notable issue is CVE-2026-18798 in OpenSSL libraries, which can cause a QUIC listener denial of service only if the container runs an OpenSSL QUIC server with HTTP/3 enabled. Because nginx does not use OpenSSL's QUIC stack in its default configuration, not enabling HTTP/3 fully eliminates this specific risk.
