Descriptions

The Patreon WordPress plugin before 1.8.2 does not sanitise and escape the field "Custom Patreon Page name", which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed

El plugin Patreon de WordPress versiones anteriores a 1.8.2, no sanea y escapa del campo "Custom Patreon Page name", lo que podría permitir a usuarios con altos privilegios llevar a cabo ataques de tipo Cross-Site Scripting incluso cuando la capacidad unfiltered_html está deshabilitada

The Patreon WordPress plugin for WordPress is vulnerable to Cross-Site Scripting in versions up to, and including, 1.8.1 due to insufficient privilege handling. This makes it possible for high-privilege users attackers to inject arbitrary web scripts that execute in a victim's browser even when the unfiltered_html capability is disallowed.
