CVE-2026-49093Network attack vector

Authenticated network access via connector allowlist bypass

Published May 28, 2026 · Updated May 28, 2026

SSRF in Elastic Kibana 9.3.0 through 9.3.2 allows remote authenticated users to reach blocked destinations through outbound server requests. Kibana connector handling fails to enforce xpack.actions.allowedHosts before issuing an outbound request. Exploitation requires connector management privileges and a non-wildcard allowlist; the default wildcard configuration is not affected.
