I would not worry about those kind of links. They are very common and Google knows very well that they are somehow automatically generated by the systems behind those sites.

Sincerely, even if they are followed, I quite confident that Google simply discount any potential PageRank (usually very minimal) those sites may pass.

Google and other search engines take into account that this is a common occurrence and they do not penalize you for having them. I wouldn't put too much energy into it.

As previously mentioned, it's natural that sites get certain links without doing anything. These types of links are natural. Typically I see many of them have nofollow attributes on their outgoing links, but some do not. I wouldn't worry too much about them. It wouldn't hurt to disavow them, but again most likely they're not going to hurt your site's rankings.
