TRUSTED

This image carries significant risk; production deployment is highly discouraged without strict compensating controls. An attacker who reaches the embedded admin server on port 8080 could slip requests past access rules through a lenient proxy, or log in with crafted digest headers if Digest authentication is enabled. Note: CVE-2026-2332 only applies when a lenient front proxy parses chunked extensions differently, and CVE-2026-10050 only applies if HTTP Digest authentication is turned on for the admin server, which is not its default setup. Keeping Digest authentication disabled on the admin server fully eliminates the exposure from CVE-2026-10050. The remaining findings are lower severity or need non-default conditions, so they do not drive this verdict.

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
