Description
WordPress Plugin Tracking Code Manager is prone to multiple vulnerabilities, including cross-site scripting and Denial of Service vulnerabilities. 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, allowing the attacker to steal cookie-based authentication credentials, or to cause the affected website to consume memory and CPU resources, thus denying service to legitimate users. WordPress Plugin Tracking Code Manager version 1.11.1 is vulnerable; prior versions may also be affected.
Remediation
Disable the plugin until a fix is available
