The WP ULike WordPress plugin before 4.7.5 does not sanitise and escape some of its settings, which could allow high privilege users such as editors to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed
The WP ULike – All-in-One Engagement Toolkit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 4.7.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
