Description
WordPress Plugin Simple Security is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input. 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. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks. WordPress Plugin Simple Security version 1.1.5 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 1.1.6 or latest
