Until an official fix is released, restrict user roles to trusted users only and monitor for suspicious activity related to the plugin's AJAX functions. Avoid granting Subscriber-level or higher access to untrusted users. Follow the vendor's updates closely for any forthcoming patches or official mitigations.
Description

This makes it possible for authenticated attackers, with Subscriber-level access and above, to compromise the site in various ways depending on the specific function exploited - for example, by retrieving sensitive settings and configuration details, or by altering and deleting them, thereby disclosing sensitive information, disrupting the plugin’s functionality, and potentially impacting overall site performance.
