{"id":"CVE-2026-10089","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-10089","generatedAt":"2026-10-28T07:03:56.772Z","title":"The Insert Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via post custom field keys (meta key names) in all versions up to, and including, 3.11.4.","description":"The Insert Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via post custom field keys (meta key names) in all versions up to, and including, 3.11.4. This is due to insufficient output escaping in the the_meta() function: while the custom field VALUE is sanitized with wp_kses_post(), the custom field KEY ($key) is interpolated into the rendered HTML (lines 1786-1791) and echoed (line 1806) without any escaping when an inserted page is rendered with the [insert page='ID' display='all'] shortcode. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","published":"2026-07-02T06:16:13.000Z","lastModified":"2026-07-02T15:16:57.000Z","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":0.00357,"percentile":0.29261,"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 (0.36%).
