This makes it possible for authenticated attackers, with subscriber-level access and above, to enumerate the complete site user roster and extract the full email address of any WordPress account, including administrator accounts, character-by-character by using the search response as an oracle against both user_login and user_email columns.","summary":"LearnPress, a WordPress course plugin, does not check user permissions on a search action, so any logged-in subscriber can query user data.
