This image poses a critical security risk and must not be used in production, especially as an internet-facing service. An attacker could exploit critical XXE vulnerabilities in Apache Tika (CVE-2025-66516) to read sensitive data or achieve remote code execution via a crafted PDF uploaded to Elasticsearch's ingest pipeline, and leverage HTTP request smuggling in Netty (CVE-2026-42581) to bypass security controls or poison caches. Disabling the Elasticsearch ingest attachment processor would fully eliminate the Tika-related vulnerabilities, but Netty smuggling requires an upgrade. Note that these vulnerabilities are reachable if the default document parsing feature is enabled.
