Facebook Page Vulnerability Security researcher Pouya Darabi has recently shared his findings regarding a major security vulnerability targeting the Facebook Page feature. Sharing the details in a blog post, Darabi revealed that the vulnerability specifically existed in the feature that manages to create hidden posts on Facebook Pages.
