 "title": "Paid Membership Subscriptions – Effortless Memberships, Recurring Payments & Content Restriction <= 3.1.3 - Unauthenticated Reflected Cross-Site Scripting via Profile Builder PayPal Redirect",
 "description": "The Paid Membership Subscriptions plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the Profile Builder PayPal redirect message in all versions up to, and including, 3.1.3, due to insufficient output escaping of the redirect URL placed in a meta refresh tag. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link, on sites where the Profile Builder plugin is active, registration pays through PayPal Standard, and Profile Builder's automatic login after registration is enabled with a non-zero redirect delay.",
