Vulnerability Description
The BUKAZU Search widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'shortcode' parameter of the 'bukazu_search' shortcode in all versions up to, and including, 3.3.2 due to insufficient input sanitization and output escaping on user supplied attributes.
