Does PRO require the same security updates as the free version?

We have been using the free version of the plugin for a while, & it recently needed updates for security reasons https://wpscan.com/plugin/ajax-login-and-registration-modal-popup.

We just purchased the PRO plugin but the version date says 2023-25-09. Does the PRO version not require the same security updates? Or it’s safe to install as is? I’m concerned because it doesn’t look like the vulnerability scanners have access to scan Pro plugins that are distributed outside of the WordPress plugin directory.

Many thanks!
