GiveWP < 4.13.1 - Unauthenticated Stored XSS via 'name'

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the ‘name’ parameter due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Avatars must be enabled in the WordPress install in order to exploit the vulnerability.
