Summary
Statamic CMS's incorrect authorization lets view-only users submit Live Preview content reserved for editors
Details

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.

Severity
3.5 (Low)
CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N
