Description
The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'slides_to_show' parameter in all versions up to, and including, 5.126.0 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.
