 "title": "Rio EMI Calculator <= 1.4.1 - Authenticated (Administrator+) Stored Cross-Site Scripting via Currency Display Setting",
 "description": "The EMI Calculator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'curr_display' value of the plugin's 'rio_settings' option in all versions up to, and including, 1.4.1, due to insufficient input sanitization when the setting is saved and missing output escaping when the value is rendered by the [rio-emi-calculator] shortcode. 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 a page containing the calculator. This only affects multi-site installations and installations where unfiltered_html has been disabled.",
