This image is acceptable for production, but remediating the identified vulnerabilities is recommended to reduce the attack surface. The main exposed issue is CVE-2026-18798 in libcrypto3/libssl3, which can cause remote denial of service of an OpenSSL QUIC listener, but it only applies if QUIC/HTTP3 is enabled and is not part of the default OpenResty configuration. No exposed findings reach severity 7.0, and the post-exploit findings are all below severity 6.0. This risk is fully avoidable by not enabling OpenSSL QUIC/HTTP3 listeners.

Scanning procedure

  1. Vulnerability scan
    Full CVE sweep across OS packages and app dependencies
  2. Exploitability check
    CVEs ranked by exploit probability (EPSS) and matched against CISA KEV
  3. Reachability analysis
    Symbol-level proof: is the vulnerable code even linked and callable in your binaries?
  4. Runtime verification
    Live-container probes: exposed endpoints, feature flags, real defaults
  5. Supply chain analysis
    Base-image lineage, package provenance and signatures — nothing slipped in unnoticed
  6. Hardening recommendations
    A hardened build plan — patch, remove unused packages, lock down the runtime — with parity tests proving nothing broke
