Researcher	Rafie Muhammad - Patchstack

Description

The Freemius SDK for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘fs_request_get’ function in versions up to, and including, 2.5.9 due to insufficient input sanitization and output escaping. 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.

Wordfence blocked 20,823,636 attacks targeting this vulnerability in the past 24 hours.
