Where does wga-cache/?C=M;O=A page indexing come from?

Question

Search Engine Optimization

Good afternoon. Who knows where the indexing of wga-cache/?C=M;O=A and uploads/?C=M;O=A pages is taken on the Wordpress site.

I suspect that it is because of the clearfy plugin.
How would you recommend avoiding this?

If you do not need any pages with parameters in the issue, then you can close them in robots.txt. For example, if I'm not mistaken, this should work: Disallow: /*?*. During a new update, the pages will have to fly out of the index
