What is CVE-2026-3309?

The ProfilePress plugin for WordPress is susceptible to a vulnerability that allows arbitrary shortcode execution. This security flaw is present in all versions up to 4.16.11 due to improper handling of user-supplied billing field values during the checkout process. Attackers can exploit this weakness by submitting specially crafted input that gets executed without adequate sanitization of shortcode syntax, enabling unauthorized shortcode commands to run. This could lead to unauthorized access or other malicious activities, emphasizing the need for prompt updates and security measures.
