Summary
The BSK PDF Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'bsk-pdfm-category-dropdown' shortcode in versions up to, and including, 3.4.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
