Input validation vulnerability in Mang Board WP 1.7.7

The Mang Board WP plugin for WordPress has a security issue that allows hackers to inject harmful scripts into pages. This can happen if the administrator settings are not properly protected. The vulnerability affects all versions up to and including 1.7.7. It means that someone with administrator-level permissions can sneak in malicious code that will run whenever a user visits the affected page. This only affects websites with multiple blogs and those that have disabled the unfiltered_html feature.
