Description
The W4 Post List plugin for WordPress is vulnerable to Stored Cross-Site Scripting via block options in versions up to, and including, 2.4.5 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.
