| Description | The JS Help Desk – AI-Powered Support & Ticketing System plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'jsticket_message' parameter in all versions up to, and including, 5.0.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload fires specifically when an administrator or agent opens the affected ticket and the page initializes VenoBox, which reads the browser-decoded data-title attribute and passes it to jQuery .html(), making routine ticket review the trigger condition. |
