Real Post Slider Lite Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Real Post Slider Lite plugin for WordPress, affecting all versions through 2.4. This vulnerability arises from inadequate input sanitization and output escaping, allowing authenticated attackers with administrator-level access to inject arbitrary scripts into pages. The injected scripts execute when a user accesses the compromised page. This issue is present in multi-site installations where the unfiltered_html capability has been disabled.

Impact

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