We have encountered a MAJOR security flaw where people can easily find part of the site that we want hidden. If this isn't the right forum, please let me know where to post it.
We are using the K2 component extension with the Uber template. When somebody Google searches our website + SuperUser (see Img01). They are able to find a list of all the K2 items created by that user (see Img02).
We DON'T want Google (or any search engine) to index these pages for any user. Can we either disable these list pages or alternatively, just stop Google from indexing them? Do we need to use a robots.txt to achieve this? Any help would be greatly appreciated!
