Description
The Mang Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting via board post content in all versions up to, and including, 2.4.4, due to insufficient input sanitization and output escaping. Content is only passed through the HTML purifier when the request includes an 'html' data_type, but posts already stored with the html data type are HTML-decoded on output without sanitization. This makes it possible for unauthenticated attackers, on boards that permit guest posting, to inject arbitrary web scripts in pages that will execute whenever a user accesses an affected page.
