What the vulnerability does

01Description

The Download Manager plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'redirect_to' parameter in all versions up to, and including, 3.3.46. This is due to insufficient input sanitization and output escaping on the 'redirect_to' GET parameter in the login form shortcode. 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

02Summary

Download Manager versions 3.3.46 and earlier contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into the application. When a victim visits a crafted page or link, the injected code executes in their browser with their permissions. The vulnerability affects multiple users and can compromise site integrity or steal user data.
