Hello. Today, new pages appeared in Yasha's webmaster panel, got into the search. All pages of this type:
https://site.ru/product-category/kremy-i-geli-dlya...

https://site.ru/product-category/kremy-i-geli-dlya...

https ://site.ru/product-category/kremy-i-geli-dlya...

https://site.ru/product-category/kremy-i-geli-dlya... ;

When you go to the page, a category page opens on which there is no listing and the answer is: No products were found matching your request.

+ in the same Yasha webmaster there were problems with Titles and descriptions, all these pages have the same title and description.

What could be the reason for such requests and page generation and how to deal with it? Thanks for the answer.

Answer 1

Well, someone tested your site for holes. If the alert does not work when clicking on any of the links, it may not be successful. But xs.
The title and descriptions of the pages are the same, probably because they all lead to the "nothing found" page.
In general, for peace of mind, you can check if you have the latest version of wp and plugins, and update if not.)

https://site.ru/product-category/kremy-i-geli-dlya-tela/?paged=;alert(31337);&max_price=;alert(31337);&min_price=;alert(31337)

Someone tried to find a vulnerability on your site. The usual thing.
A good reason to remember when was the last time the CMS and its plugins were updated.
