Your website is affected if you are using WP Mail SMTP version 4.0.1 or earlier. To check your plugin version, go to the WordPress dashboard, navigate to the 'Plugins' section, and find WP Mail SMTP in the list. The version number will be displayed there.

If you find that you are using an affected version, it's important to update immediately to the latest version, 4.1.0 or higher. Additionally, reviewing your site’s access logs for any unusual activity can help identify potential exploitation.

Such actions could damage your site’s reputation and trustworthiness.

In a worst-case scenario, sensitive information could be compromised, leading to data breaches. This could include personal information of users or clients, which could result in legal consequences and loss of customer trust.
