WordPress ActiveHelper LiveHelp Live Chat Plugin Multiple Cross Site Scripting Vulnerabilities

ActiveHelper LiveHelp Live Chat plugin for WordPress is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input.

An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.

ActiveHelper LiveHelp Live Chat 3.1.0 is vulnerable; other versions may also be affected.
