CVE-2026-15284 Details
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.
A stored cross-site scripting vulnerability has been identified in the King Addons for Elementor WordPress plugin, affecting versions through 51.1.62. The issue arises from inadequate input sanitization in the 'add_to_submissions()' function, which uses 'sanitize_text_field()'—a method that retains double-quote characters—before saving the data to post meta. This flaw is compounded by a lack of proper output escaping in the 'king_addons_submissions_custom_column_content()' function, which directly adds the stored value into an HTML href attribute via 'admin_url()' without using 'esc_url()' to sanitize it. As a result, authenticated attackers with subscriber-level access or higher can inject malicious scripts into pages, where they will be executed when a user views the affected page.
Users are advised to update the King Addons for Elementor plugin to version 51.1.63 or later, where this vulnerability has been patched.
