The HT Mega – Absolute Addons For Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability in its lightbox widget. This occurs because the plugin does not properly sanitize or escape user input before rendering it in web pages. Authenticated users with contributor-level or higher permissions can exploit this to inject arbitrary JavaScript code that executes in the context of other users visiting the compromised pages. This vulnerability affects all plugin versions up to and including 2.4.6. The CVSS 3.1 base score is 6.4, reflecting a network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity but not availability.

An attacker with contributor-level or higher permissions can inject malicious scripts into pages via the vulnerable lightbox widget. These scripts execute in the browsers of users who view the injected pages, potentially leading to theft of sensitive information, session hijacking, or other client-side impacts. The vulnerability does not affect availability and requires authenticated access, limiting the scope of exploitation.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level permissions to trusted users only and consider disabling or avoiding use of the lightbox widget in the HT Mega Addons for Elementor plugin. Monitor vendor channels for updates and apply patches promptly once available.
