View the ranked messenger users for any page
In Creator Studio there is a new feature to rank messenger users. This isn’t scoped to admins so a user can see which of their friends messaged any page.graphql?doc_id=3204638226276173&variables={pageID:113702895386410}
For pages where the admin disabled messaging, this also causes a page admin disclosure as the the only users still on the list will be those with admin roles who can test messaging on the page. The caveat is the user (with the admin role) must have messaged the page.
Impact
An attacker can see which of their friends have messaged a particular page.
