Description
WordPress Plugin LayerSlider is prone to multiple vulnerabilities, including cross-site scripting, cross-site request forgery and SQL injection 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, to perform certain administrative actions and gain unauthorized access to the affected application or to compromise the application, access or modify data or to exploit vulnerabilities in the underlying database. WordPress Plugin LayerSlider version 6.2.0 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 6.2.1 or latest
