What is CVE-2016-20066?

The WordPress CP Polls plugin version 1.0.8 contains a vulnerability that allows for persistent cross-site scripting (XSS) attacks due to insufficient validation in its file upload feature. This flaw enables malicious actors to upload files with embedded scripts, which can execute arbitrary JavaScript in the browsers of users who access the infected content. As a result, attackers can potentially hijack user sessions, steal cookies, or perform other malicious actions against unaware users. Proper input sanitization and implementing security measures are essential to mitigate this vulnerability.
