TRUSTED

This image poses a critical security risk and must not be used in production, especially as an internet-facing service. Exploitation could allow an attacker to bypass gRPC authorization (CVE-2026-33186) and gain unauthorized access to sensitive data or execute arbitrary code via container image cache poisoning (CVE-2026-50195). Note: CVE-2026-33186 only applies if path-based authorization interceptors are configured, and CVE-2026-50195 requires the attacker to have pod creation permissions. Despite originating from a trusted publisher, the presence of these high-severity vulnerabilities warrants immediate remediation or image replacement.

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
