## Description

The WindPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Gutenberg Common Block's attributes and content in all versions up to, and including, 3.2.94 due to insufficient input sanitization and output escaping. The block allowed dangerous tag names such as script, arbitrary attribute names including on* event handlers, a double entity-decoded and unescaped className, and raw text content. 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.
