Description
The List Attachments Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'before_list' parameter in the [list-attachments] shortcode in all versions up to, and including, 0.4.1a due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
