Description

The Visualizer – Tables & Charts Manager with Built-in AI Generator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'backend-title' parameter in all versions up to, and including, 4.0.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
