The Paid Memberships Pro plugin for WordPress is vulnerable to unauthorized modification and disruption of Stripe webhook configuration in all versions up to, and including, 3.6.5. This is due to missing capability checks on the `wp_ajax_pmpro_stripe_create_webhook`, `wp_ajax_pmpro_stripe_delete_webhook`, and `wp_ajax_pmpro_stripe_rebuild_webhook` AJAX handlers. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete, create, or rebuild the site's Stripe webhook, disrupting all payment processing, subscription renewal synchronization, cancellation handling, and failed payment management.

The Paid Memberships Pro – Content Restriction, User Registration, & Paid Subscriptions plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.12.10. This is due to missing or incorrect nonce validation on multiple functions. This makes it possible for unauthenticated attackers to subscribe to, modify, or cancel membership for a user via a forged request granted they can trick a user into performing an action such as clicking on a link.

Multiple cross-site scripting (XSS) vulnerabilities in the Paid Memberships Pro (PMPro) plugin before 1.8.4.3 for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) s parameter to membershiplevels.php, (2) memberslist.php, or (3) orders.php in adminpages/ or the (4) edit parameter to adminpages/membershiplevels.php.
