## Description

The Products Suggestions for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the suggestion condition settings in all versions up to, and including, 3.6.4, due to insufficient sanitization of the array keys of submitted condition groups and conditions, and missing escaping when those keys are printed into HTML attributes by the conditions builder. The Suggestion post type uses the standard 'post' capabilities, so any user who can edit posts can create a suggestion. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts that execute when a user, such as an administrator, opens the suggestion's edit screen.
