CVE-2026-54244: Statamic CMS's incorrect authorization lets view-only users submit Live Preview content reserved for editors

June 26, 2026

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.
