CVE-2025-13840

medium

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. 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.
