Vulnerability Overview

The Category Post List Widget plugin for WordPress is vulnerable to stored Cross-Site Scripting via the ‘custom_css’ parameter in versions up to, and including, 2.0 due to insufficient input sanitization and output escaping and a lack of a nonce check on the 'get_cplw_settings' function. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
