This behavior occurs when there is an installed verification callback that instructs the verifier to continue upon detecting an invalid certificate.","published":"2023-04-12T05:15:08.000Z","lastModified":"2026-06-17T05:15:25.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"},"cwe":["CWE-295"],"affected":["openbsd/libressl","openbsd/openbsd"],"epss":{"score":0.00362,"percentile":0.29726,"date":"2026-10-26","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 (0.36%).
