What the vulnerability does
The Post Like Dislike plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the `$_SERVER['PHP_SELF']` variable in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The vulnerability requires user interaction and can affect other users on the site. Update to a version newer than 1.0 to resolve this issue.
What an attacker can do

Potential impact on your site
Users visiting affected pages may have their sessions compromised or be tricked into performing unwanted actions.
