What is CVE-2015-10143?

The Platform theme for WordPress is susceptible to a significant security flaw that allows unauthorized users to modify data through the *_ajax_save_options() function. This vulnerability stems from the absence of a capability check, enabling attackers to change site options, such as elevating their user roles to administrator. As a result, unauthenticated attackers can exploit this weakness to gain unauthorized administrative privileges on WordPress sites. It is essential for users of the Platform theme to secure their installations and apply any patches to mitigate this risk.
