CVE-2021-24228 Information

Description

The Jetpack Scan team identified a Reflected Cross-Site Scripting in the Login Form of the Patreon WordPress plugin before 1.7.2. The WordPress login form (wp-login.php) is hooked by the plugin and offers to allow users to authenticate on the site using their Patreon account. Unfortunately some of the error logging logic behind the scene allowed user-controlled input to be reflected on the login page unsanitized.
