Is WooCommerce secure to use with Multisite and open registration?

@kiberchaka WooCommerce uses the core WordPress registration functionality. It does not add its own registration system. So, it will be as secure as the core WordPress registration process is.

Do you have any particular concerns about security in a multisite? I’m not sure I understand your questions, so the more context we have, the better.

Hi, Fernando!
Thank you for the answer!
I mean, not specific registration security problems, but all possible security problems, for example will it be possible to hack database or other people blogs in same network? for a user, that will have a blog with WC enabled in WP Multisite network.
I told about registration, because I wont it to be open for everyone, so my concerns are about some peoples that will register, recive blog with WooCommerce enabled and hack all network thru WooCommerce somehow.
For example, when they will create an item (WC custom post type), can they make DB injection or include a JS?
I am not a security expert, so I will appreciate any thoughts.
Sorry for my English.

@kiberchaka It sounds like your questions are more focused on the overall security of a WordPress website – which isn’t specific to the WooCommerce plugin.

I’d recommend doing a bit of reading on general security tips for a WordPress/WooCommerce site. Here are a couple of good articles that touch on the subject:
