TRUSTED

This image poses a critical security risk and must not be used in production, especially as an internet-facing service. An attacker could smuggle requests past access rules on the admin port 8080 and bypass authentication, and because the container runs as root by default, the consequences of a compromise are amplified. Note: CVE-2026-10050 only applies if HTTP Digest authentication is configured on the admin server. Its official-image provenance does not change the exposed-surface findings that drive this verdict.
