Name of the Vulnerable Software and Affected Versions Booking.com Product Helper WordPress plugin versions prior to 1.0.2

Description The issue allows high privilege users to perform Cross-Site Scripting attacks due to the lack of sanitization and escaping of the Product Code when creating Product Shortcode. This is possible even when the unfiltered html capability is disallowed.

Recommendations For versions prior to 1.0.2, update to version 1.0.2 or later to resolve the issue. As a temporary workaround, consider restricting the ability to create Product Shortcodes to trusted users only until the update is applied.
