This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload persists in wp_comments.comment_author independently of the user account, so removing or changing the attacker's display name after the comment is posted does not neutralize the stored script.","published":"2026-10-16T06:17:06.000Z","lastModified":"2026-10-16T15:17:05.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":6.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},"cwe":["CWE-79"],"affected":[],"epss":{"score":0.00195,"percentile":0.09139,"date":"2026-10-27","history":[{"date":"2026-10-16","score":0.00201,"percentile":0.09303}]},"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 (0.19%).
