## Description

The IMPress for IDX Broker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via listing details (such as the disclaimer, open house, price and zip fields) in all versions up to, and including, 3.3.1, due to insufficient input sanitization when the 'wp_listings' meta box fields are saved and insufficient output escaping when the values are displayed in listing templates and by the 'listings' and 'wp_listings_meta' shortcodes. 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.
