What is CVE-2026-3568?

The MStore API plugin for WordPress is susceptible to an Insecure Direct Object Reference due to improper handling of the 'meta_data' JSON parameter in the update_user_profile() function. This vulnerability allows authenticated attackers with Subscriber-level access and above to manipulate arbitrary user meta fields, potentially modifying sensitive data such as user levels and specific plugin authorizations without adequate validation or sanitization. Attackers could exploit this to perform unauthorized actions, including privilege escalation and possibly introducing Stored XSS vulnerabilities in admin contexts.
