Patreon WordPress <= 1.7.0 - Reflected Cross-Site Scripting

The Jetpack Scan team identified a Reflected Cross-Site Scripting via the patreon_save_attachment_patreon_level AJAX action of the Patreon WordPress plugin before 1.7.2. This AJAX hook is used to update the pledge level required by Patreon subscribers to access a given attachment. This action is accessible for user accounts with the ‘manage_options’ privilege (i.e.., only administrators). Unfortunately, one of the parameters used in this AJAX endpoint is not sanitized before being printed back to the user, so the risk it represents is the same as the previous XSS vulnerability.

Quick Answer

CVE-2021-24229 is a critical severity with CVSS 9.6 Cross-Site Scripting issue affecting the Plugin Patreon WordPress. It affects Versions before 1.7.2 and is fixed in 1.7.2.
