Description

The Mang Board WP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the board_header and board_footer parameters in all versions up to, and including, 1.8.6 due to insufficient input sanitization and output escaping.

This only affects multi-site installations and installations where unfiltered_html has been disabled.
