RELIABLE

This image is acceptable for production, but remediating the identified vulnerabilities is recommended to reduce the attack surface. The scan found 55 vulnerabilities in total, and the four most relevant ones carry a severity of 6.0 with none known to be actively exploited. The most significant is CVE-2026-33487, an authentication bypass that only matters if SAML single sign-on is enabled, so leaving that feature off removes this path. The remaining findings are denial-of-service issues that depend on specific features or direct HTTP/2 exposure, and they are unlikely to compromise data but could slow or stall the service under abuse. Updating the affected Go dependencies in the next image build would address these findings.

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
