WordPress Count Per Day Plugin - Cross Site Scripting
Count per Day
WordPress Count Per Day plugin's "daytoshow" parameter is prone to a cross-site scripting vulnerability. It fails to properly clean up user-supplied input. An attacker may execute arbitrary script code in the browser of an user in the context of the affected site. In this way the attacker can steal cookie-based authentication credentials. Other attacks are also possible.
Update the plugin.
