Can you explain this vulnerability to me?
The Broadstreet plugin for WordPress has a vulnerability called Insecure Direct Object Reference (IDOR) in all versions up to and including 1.52.2. This occurs via the get_sponsored_meta AJAX action because it lacks proper validation on a user-controlled key.
This flaw allows authenticated users with Subscriber-level access or higher to access private post metadata that they should not be able to see.
How can this vulnerability impact me? :
This vulnerability can lead to unauthorized disclosure of private post metadata within a WordPress site using the Broadstreet plugin. Even users with low-level access (Subscribers) can exploit this to view sensitive information that is meant to be private.
Such unauthorized data exposure can compromise confidentiality and potentially lead to further security issues depending on the nature of the private metadata disclosed.
