HT Mega – Absolute Addons For Elementor DOM-Based Stored Cross-Site Scripting Vulnerability

A DOM-based stored cross-site scripting vulnerability has been identified in the HT Mega – Absolute Addons For Elementor plugin for WordPress, affecting all versions through 2.8.2. The issue arises in the Countdown widget, where inadequate input sanitization and output escaping on user-supplied attributes allow authenticated attackers with contributor-level access or higher to inject arbitrary web scripts. These scripts execute when a user accesses the compromised page. This vulnerability is a result of an incomplete fix for CVE-2024-3307.

Impact

Exploitation of this vulnerability allows for DOM-based stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Remediation

Users are advised to update the HT Mega – Absolute Addons For Elementor plugin to version 2.8.3 or a newer patched version.
