It is important to note that even if you are not actively using the vulnerable shortcode (su_members), your website is still at risk if you have the plugin installed and activated.

While many web hosting providers offer some level of security for their customers' websites, it is ultimately the responsibility of the website owner to ensure their site is secure and up-to-date.

Hosting providers may have security measures in place to protect their servers and infrastructure, but they cannot control the plugins, themes, and content you install on your website. Therefore, it is crucial to take proactive steps to secure your WordPress site, such as updating plugins and themes, implementing security best practices, and regularly monitoring for potential threats.

To stay informed about plugin updates, you can:

Regularly check your WordPress dashboard for update notifications
Subscribe to plugin developers' newsletters or social media channels to receive update announcements
Use a WordPress management tool that notifies you of available updates and allows you to update plugins with a single click

By keeping your plugins up-to-date, you can minimize the risk of your website being compromised due to known vulnerabilities.
