CVE-2026-17605
The Payment forms, Buy now buttons, and Invoicing System | GetPaid plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.8.56 via the getpaid_payment_form_element function. This makes it possible for authenticated attackers, with administrator-level access and above, to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included.
