View all Paid Memberships Pro – Content Restriction, User Registration, & Paid Subscriptions vulnerabilities

Vulnerability Overview

The Paid Memberships Pro – Content Restriction, User Registration, & Paid Subscriptions plugin for WordPress is vulnerable to unauthorized modification of membership levels created by the plugin due to an incorrectly implemented capability check in the pmpro_rest_api_get_permissions_check function in all versions up to 2.12.5 (inclusive). This makes it possible for unauthenticated attackers to change membership levels including prices.

Technical Analysis

REMEDIATION: Update to version 2.12.6, or a newer patched version --- IDENTIFIER: CWE-862 (Missing Authorization) The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
