Duplicated category URLs

[riccardo.raneri]

When using nested categories, every URL that ends with a valid category slug works. For example (using WooCommerce, but you get the same with the standard WP structure, "category" instead of "products"):

• ​http://www.example.com/products/pasta-and-risotto/pasta/
• ​http://www.example.com/products/a-random-slug/pasta/
• ​http://www.example.com/products/pasta/

In this example, "pasta" is a subcategory of "pasta-and-risotto". If you go to the three URLs above you'll get the same page.

This is wrong from a logic point of view, because only the first URL is correct (it respects the structure of categories I have set in the admin interface -- in fact, the automatic navigation menu links to this one). In addiction of this, it generates duplicated content.
