Source record

Technical description

The Font Awesome 4 Menus plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fa' and 'fa-stack' shortcodes in versions up to, and including, 4.7.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
