AI-suggested
Users should monitor the vendor's advisory for updates. Until a fix is released, avoid exposing the plugin's system_requirements stage to untrusted users and exercise caution with links involving the 'host' parameter.
Description
The SSL Zen — SSL Certificate Installer & HTTPS Redirects plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'host' parameter in all versions up to, and including, 4.7.42 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 is only exploitable when in the system_requirements stage.
