Input validation vulnerability in Paid Memberships Pro – Restrict Member Access to Content, Courses, Communities – Free or Paid Subscriptions 2.5.0

The Paid Memberships Pro plugin for WordPress is vulnerable to a type of attack called Cross-Site Scripting. This type of attack is possible in versions up to and including 2.5.0 because the plugin does not properly secure user input and does not escape output properly. This means that attackers can inject malicious scripts into the plugin which can then run in a victim’s browser.
