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."}], "title": "Insert Pages <= 3.11.4 - Authenticated (Author+) Stored Cross-Site Scripting via Custom Field Keys (Meta Key Names)", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/a4246181-d331-46b0-ad48-e2ece11b2f5f?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/insert-pages/tags/3.11.4/insert-pages.php#L1789"}, {"url": "https://plugins.trac.wordpress.org/browser/insert-pages/tags/3.11.4/insert-pages.php#L1771"}, {"url": "https://plugins.trac.wordpress.org/browser/insert-pages/tags/3.11.4/insert-pages.php#L768"}, {"url": "https://plugins.trac.wordpress.org/browser/insert-pages/tags/3.11.3/insert-pages.php#L1789"}, {"url": "https://plugins.trac.wordpress.org/browser/insert-pages/tags/3.11.3/insert-pages.php#L1771"}, {"url": "https://plugins.trac.wordpress.org/browser/insert-pages/tags/3.11.3/insert-pages.php#L768"}, {"url": "https://plugins.trac.wordpress.org/changeset/3579298"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')", "cweId": "CWE-79", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N", "baseScore": 6.4, "baseSeverity": "MEDIUM"}}], "credits": [{"lang": "en", "type": "finder", "value": "Athiwat Tiprasaharn (Jitlada)"}], "timeline": [{"time": "2026-06-19T23:06:54.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-07-01T17:21:08.000Z", "lang": "en", "value": "Disclosed"}]}}}
