## Description

The Paid Membership Subscriptions plugin for WordPress is vulnerable to SQL Injection via the 'pms-view' parameter of the Members list table in versions 1.8.5 to 3.1.1. This is due to insufficient escaping on the user-supplied parameter and lack of sufficient preparation on the existing SQL queries: the subscription status value was built into the members and member subscriptions query strings instead of being bound as a placeholder. The Members list table query runs on the current_screen hook without a capability check, so any authenticated user can trigger it. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries to existing queries and extract sensitive information from the database.
