This image carries significant risk; production deployment is highly discouraged without strict compensating controls. An attacker who sends crafted traffic could crash the proxy and interrupt the services behind it, and the known-exploited Brotli flaw could allow code execution if decompression is enabled. Note: CVE-2026-111497 only applies when a Brotli decompression filter is active, and CVE-2021-39155 and CVE-2021-39156 only apply when Istio authorization policies match on host or path. Keeping Brotli decompression disabled removes the path that CVE-2026-111497 needs, and the image runs as root by default, which increases the impact of any compromise.
