The Common Ninja: Fully Customizable & Perfectly Responsive Free Widgets for WordPress Websites plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'commonninja' shortcode in all versions up to, and including, 1.1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Easily Generate Rest API Url WordPress plugin through 1.0.0 does not escape some of its settings, allowing high privilege users such as admin to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed
