This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. WordPress's save-time wp_kses_post does not neutralize the payload because the attack is delivered via shortcode attributes rather than raw HTML in post content, allowing the unescaped values to survive to render time.","published":"2026-10-10T06:16:42.000Z","lastModified":"2026-10-13T13:30:22.000Z","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":0.09127,"date":"2026-10-26","history":[{"date":"2026-10-10","score":0.00201,"percentile":0.09159}]},"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%).
