Elements Plus! WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Elements Plus! plugin for WordPress, affecting all versions through 2.16.4. The issue arises from inadequate input sanitization and output escaping on user-supplied attributes in the plugin's Image Comparison, HotSpot Plus, and Google Maps widgets. This vulnerability allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts into pages, which are executed when users access the affected pages.

Impact

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