Description

The Gravity Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 2.10.0. This is due to insufficient validation and output escaping of Product Option field values. The vulnerability exists because the state validation function accepts submitted values where the wp_kses()-sanitized version matches a legitimate option value, but then stores the raw unsanitized value in the database. When administrators view entry details via the Order Summary section, the option_label is output directly without escaping (view-order-summary.php line 32), executing the injected JavaScript. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in entry data that will execute whenever an administrator accesses the entry details page.
