CVE-2026-0844

What is CVE-2026-0844?

The Simple User Registration plugin for WordPress suffers from a vulnerability that allows authenticated users with minimal permissions to escalate their privileges. This occurs due to inadequate safeguards in the 'profile_save_field' function, enabling subscribers to modify their user role by manipulating the 'wp_capabilities' parameter during profile updates. Such an exploit could lead to unauthorized access and potential control over user accounts, posing a significant risk to website security.
