If reloading the trust material fails the trust manager will be replaced with an instance that trusts all certificates. This could allow any node using any certificate to join a cluster. The proper behavior in this instance is for the TLS trust manager to deny all certificates.","published":"2017-08-18T20:29:00.000Z","lastModified":"2026-06-17T01:26:23.000Z","status":"Modified","sourceIdentifier":"security@elastic.co","cvss":{"version":"3.0","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},"cwe":["CWE-295"],"affected":["elastic/x-pack"],"epss":{"score":0.0016,"percentile":0.05106,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.16%).
