XSS in Devitemsllc Ht Mega Addons For Elementor – Widgets & Template Builder
CVE-2026-111318
The HT Mega Addons for Elementor – Elementor Widgets & Template Builder plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'href attribute of <a> inside .htmega-tab-nav' parameter in all versions up to, and including, 3.2.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires a co-installed plugin such as wpDiscuz with its rich editor enabled whose markup allowlist permits span[class] and a[href] storage, an HT Mega Tabs widget present on the same page as the comment section, and a victim user click on the injected anchor link.
