Statamic CMS's incorrect authorization lets view-only users submit Live Preview content reserved for editors
Impact
The Live Preview endpoint for existing entries and terms only checked view authorization, but it accepts and renders caller-supplied field values. A Control Panel user with view but not edit permission could therefore submit content they were not authorized to author and generate a shareable Live Preview URL rendering it.
Patches
This has been fixed in 5.74.0 and 6.20.3.
