Description
The OAuth Single Sign On plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the configured application name in all versions up to, and including, 7.1.4. This is due to insufficient output escaping: the name is placed inside an inline onClick JavaScript handler of the SSO login button using only esc_attr(). This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts that will execute when a user clicks the login button on a page displaying it. This only affects multi-site installations and installations where unfiltered_html has been disabled.
