Summary

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.

Affected Version(s)

Paid Memberships Pro – Content Restriction, User Registration, & Paid Subscriptions * <= 2.12.3
