 "title": "Site Reviews <= 8.3.3 - Authenticated (Subscriber+) Missing Authorization to User Information Exposure via REST Shortcode Options Endpoint",
 "description": "The Site Reviews plugin for WordPress is vulnerable to unauthorized access of data via the REST API shortcode options route in all versions up to, and including, 8.3.3 due to a missing capability check in the checkShortcodePermission function, which only verified that the requester was logged in. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve the shortcode option lists, which include the site's users, and thereby enumerate user names regardless of their role.",
