What the vulnerability does
The Download Manager plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘user_ids’ parameter in all versions up to, and including, 3.3.23 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.

An attacker can inject malicious scripts that execute in a victim's browser when they visit a crafted link. The vulnerability requires user interaction and can affect other users or the site itself depending on context. Update to a version newer than 3.3.23.
What an attacker can do
Inject malicious scripts that run in a victim's browser when they click a link or visit a page.
Potential impact on your site
