Statamic's Markdown preview endpoint exposes sensitive user data

Statamic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.16 and 6.7.2, the markdown preview endpoint could be manipulated to return augmented data from arbitrary fieldtypes. With the users fieldtype specifically, an authenticated control panel user could retrieve sensitive user data including email addresses, encrypted passkey data, and encrypted two-factor authentication codes. This has been fixed in 5.73.16 and 6.7.2.
