CVE-2026-63142Network attack vector

Authenticated SSRF via incomplete destination denylist

Published Jul 21, 2026 · Updated Jul 21, 2026

SSRF in Elastic Kibana allows remote authenticated users with Reporting access to make the service contact denied network destinations. The Reporting service checks crafted destination input against an incomplete set of disallowed values, permitting requests that evade administrator-configured outbound restrictions. Reaching the flaw requires Kibana credentials and Reporting access; the bounded result is indirect disclosure from network destinations reachable by the server.
