Description

The Paid Memberships Pro plugin for WordPress is vulnerable to SQL injection in versions before 2.9.8 via the 'code' parameter in the /pmpro/v1/order REST route. This allows unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
