What the vulnerability does
The wordpress vertical image slider plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘search_term’ parameter in versions up to, and including, 1.2.16 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.
Explanation of Vulnerability in Simple Terms

An attacker can inject malicious scripts that execute in a visitor's browser when they view a page containing the slider. The vulnerability requires user interaction—the victim must visit a crafted page—but can affect other users and steal session data or credentials.
What an attacker can do
Inject malicious JavaScript that runs in visitors' browsers and steals session cookies or credentials.
Potential impact on your site
