WordPress Core is vulnerable to Sensitive Information Exposure in all versions up to, and including, 7.0.2 via the comment feeds due to insufficient restrictions on internal notes, which are not excluded from feed output. This makes it possible for unauthenticated attackers to extract the contents of internal notes that should only be available to privileged users.
