{"id":"CVE-2026-115869","published":"2026-10-30T18:17:23.393","lastModified":"2026-10-30T19:18:13.057","description":"The Themify Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'variations' repeater field of Custom Font (tb_cf) posts in versions up to, and including, 7.8.4. This is due to insufficient input sanitization and output escaping on the variations post meta: Themify_Metabox::_save_meta() only passes the value through wp_kses_data() when the field type is 'textbox' or 'textarea', so the 'repeater' field writes attacker-controlled sub-fields (style, woff/woff2/ttf/svg/eot URLs) to update_post_meta() verbatim, and Themify_Custom_Fonts::render_columns() later echoes those values unescaped inside a <style> block on the Custom Fonts admin listing. 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 (specifically, the Custom Fonts admin listing).","cvssScore":6.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.8.4/themify/class-themify-custom-fonts.php#L287","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.8.4/themify/themify-metabox/includes/themify-metabox-core.php#L208","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/themify-builder/tags/7.8.4/themify/themify-metabox/includes/themify-metabox-core.php#L230","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3774070%40themify-builder&new=3774070%40themify-builder","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/cf80f304-f79d-4863-b57a-d273daa5fe7f?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
