Description
The MoreConvert Wishlist for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'empty_icon' and 'has_item_icon' attributes of the [wlfmc_wishlist_counter] shortcode in all versions up to, and including, 2.0.3, due to insufficient input sanitization and output escaping. The attribute values are HTML-entity-decoded twice and concatenated unescaped into icon markup, which the plugin's front-end script later inserts into the page as HTML. 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.
