What is CVE-2023-6187?

The Paid Memberships Pro plugin for WordPress is affected by a vulnerability allowing authenticated users with subscriber privileges or higher to upload arbitrary files. This occurs due to inadequate file type validation in the 'pmpro_paypalexpress_session_vars_for_user_fields' function. If the payment method is set to PayPal Express or the deprecated 2Checkout and a custom user field is configured to be visible in the profile, attackers can exploit this vulnerability to potentially execute remote code on the affected site's server.
