Threat Score
50/100CAUTION
Reputation
TRUSTED

This image carries significant risk; production deployment is highly discouraged without strict compensating controls. An attacker could exploit exposed Jackson issues such as CVE-2026-89425 and CVE-2026-91776 to cause resource exhaustion and disrupt Elasticsearch availability. The image is official and digest-pinned, and the scan shows no exposed findings at severity 7.0 or higher, but there are still 45 exposed vulnerabilities with 7 at severity 6.0 or higher. CVE-2026-91776 only applies if name-based polymorphism with a default fallback is enabled, and disabling that configuration would fully eliminate that specific risk.
