Description
WordPress Plugin SG Optimizer is prone to multiple vulnerabilities, including cross-site scripting, security bypass 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, to steal cookie-based authentication credentials, to perform otherwise restricted actions and subsequently change plugin's settings, or to perform certain administrative actions and gain unauthorized access to the affected application. WordPress Plugin SG Optimizer version 3.3.5 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 4.0.0 or latest
