@officezen – Try v2.6.0.
To be clear it is both true, but also a false positive in how it is represented based on generic categorization.
It did not allow any hacking of your site for example, but if you had set up specific features so that your content showed “Restricted Content” notices but still appeared in archives or search results, then someone could effectively guess your content & expose it with repeated searches. Ultimately WP core’s search showing results (which is what was set up by the admin), actually confirms the searched content exists in the restricted item.
You can read about this specific issue here:?https://contentcontrolplugin.com/docs/security/preventing-bots-from-discovering-restricted-content/#how-content-can-be-exposed
Now its removed from search by default, and if you turn it on you basically have to acknowledge you know what your doing.
