A severe protection imperfection impacted the Facebook Post Page function
… that might possibly cause a mess for the admins. As revealed, exploiting this Facebook Page susceptability could enable a foe to produce undetectable posts on the target web pages.

Sharing the details in an article, Darabi exposed that the susceptability specifically existed in the feature that manages to develop covert blog posts on Facebook Pages.
These “invisible” blog posts do not appear publicly. It indicates they are non listed from the feed. Yet, they create an ID as well as a link that reroute anybody with the link to the post.
