{"id":"CVE-2026-15284","state":"PUBLISHED","title":"King Addons for Elementor <= 51.1.62 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'form_page_id' Parameter","description":"The King Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form_page_id' parameter in versions up to, and including, 51.1.62 This is due to insufficient input sanitization in the add_to_submissions() function, which applies sanitize_text_field() (which preserves double-quote characters) before storing the value in post meta, combined with missing output escaping in the king_addons_submissions_custom_column_content() function, which concatenates the stored value into an HTML href attribute via admin_url() without wrapping the result in esc_url(). 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.","publishedAt":"2026-07-10T04:31:21.383Z","updatedAt":"2026-07-10T20:31:09.070Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["kingaddons King Addons for Elementor – 80+ Elementor Widgets, 4 000+ Elementor Templates, WooCommerce, Mega Menu, Popup Builder"],"affected":[{"vendor":"kingaddons","product":"King Addons for Elementor – 80+ Elementor Widgets, 4 000+ Elementor Templates, WooCommerce, Mega Menu, Popup Builder","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"51.1.62","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/349ba9de-69b3-42fb-aeba-c3a24280547f?source=cve","https://plugins.trac.wordpress.org/browser/king-addons/tags/51.1.62/includes/widgets/Form_Builder/helpers/View_Submissions_Pro.php#L305","https://plugins.trac.wordpress.org/browser/king-addons/tags/51.1.62/includes/widgets/Form_Builder/helpers/Create_Submission.php#L68","https://plugins.trac.wordpress.org/browser/king-addons/tags/51.1.62/includes/widgets/Form_Builder/helpers/Upload_Email_File.php#L261","https://plugins.trac.wordpress.org/browser/king-addons/tags/51.1.61/includes/widgets/Form_Builder/helpers/View_Submissions_Pro.php#L305","https://plugins.trac.wordpress.org/browser/king-addons/tags/51.1.61/includes/widgets/Form_Builder/helpers/Create_Submission.php#L68","https://plugins.trac.wordpress.org/browser/king-addons/tags/51.1.61/includes/widgets/Form_Builder/helpers/Upload_Email_File.php#L261","https://plugins.trac.wordpress.org/changeset?old_path=%2Fking-addons/tags/51.1.62&new_path=%2Fking-addons/tags/51.1.63","https://plugins.trac.wordpress.org/changeset/3537725/king-addons/tags/51.1.63/includes/widgets/Form_Builder/helpers/Create_Submission.php?old=3515422&old_path=king-addons%2Ftags%2F51.1.62%2Fincludes%2Fwidgets%2FForm_Builder%2Fhelpers%2FCreate_Submission.php","https://plugins.trac.wordpress.org/changeset/3537725/king-addons/tags/51.1.63/includes/widgets/Form_Builder/helpers/View_Submissions_Pro.php?old=3515422&old_path=king-addons%2Ftags%2F51.1.62%2Fincludes%2Fwidgets%2FForm_Builder%2Fhelpers%2FView_Submissions_Pro.php"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15284.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15284","state":"PUBLISHED","datePublished":"2026-07-10T04:31:21.383Z","dateUpdated":"2026-07-10T20:31:09.070Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-09T15:49:20.495Z"},"containers":{"cna":{"title":"King Addons for Elementor <= 51.1.62 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'form_page_id' Parameter","descriptions":[{"lang":"en","value":"The King Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form_page_id' parameter in versions up to, and including, 51.1.62 This is due to insufficient input sanitization in the add_to_submissions() function, which applies sanitize_text_field() (which preserves double-quote characters) before storing the value in post meta, combined with missing output escaping in the king_addons_submissions_custom_column_content() function, which concatenates the stored value into an HTML href attribute via admin_url() without wrapping the result in esc_url().
