Easy Table of Contents < 2.0.79 - Contributor+ Stored XSS

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the plugin's `ez-toc` shortcode 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.
