Name of the Vulnerable Software and Affected Versions The Shield Security plugin for WordPress versions prior to 21.0.9

Description The Shield Security plugin for WordPress is susceptible to Reflected Cross-Site Scripting. This is due to inadequate input sanitization and output escaping of the message parameter.
