The Paid Memberships Pro WordPress plugin before 2.9.9 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.

SQL injection vulnerability in the Paid Memberships Pro versions prior to 2.5.6 allows remote authenticated attackers to execute arbitrary SQL commands via unspecified vectors.

The Paid Memberships Pro plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.4.2. This is due to missing or incorrect nonce validation on the pmpro_page_save() function. This makes it possible for unauthenticated attackers to save pages via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
