Until an official fix is available, restrict administrator access to trusted users only and consider disabling or removing the Mandatory Field plugin in multi-site environments or where unfiltered_html is disabled. Monitor official sources for updates or patches addressing this vulnerability.
Description
The Mandatory Field plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.6.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
