SellKit – Funnel builder and checkout optimizer for WooCommerce to sell more, faster <= 1.9.8 - Authenticated (Contributor+) Stored Cross-Site Scripting via id Parameter

Description The SellKit – Funnel builder and checkout optimizer for WooCommerce to sell more, faster plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘id’ parameter in all versions up to, and including, 1.9.8 due to insufficient input sanitization and output escaping. 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.
