Description

The W4 Post List plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘w4pl[no_items_text]' parameter in versions up to, and including, 2.4.4 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.
