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, 2.4.7, due to content only being purified on save when the user-supplied 'data_type' parameter contains 'html', the 'data_type' value being updatable on modification without resubmitting content, and HTML content only being purified on output for posts written by guests (level 0). This makes it possible for authenticated attackers with board member access (Subscriber-level) and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
