Description

WordPress Plugin Gwolle Guestbook is prone to multiple vulnerabilities, including cross-site scripting and cross-site request forgery vulnerabilities. Exploiting these issues could allow an attacker to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, allowing the attacker to steal cookie-based authentication credentials and launch other attacks, or to perform certain administrative actions and gain unauthorized access to the affected application. WordPress Plugin Gwolle Guestbook version 2.1.0 is vulnerable; prior versions may also be affected.

Remediation

Update to plugin version 2.1.1 or latest
