Description
Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.74.0 and 6.20.3, the Live Preview endpoint for existing entries and terms in src/Http/Controllers/CP/PreviewController.php 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. This issue is fixed in versions 5.74.0 and 6.20.3.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for statamic/cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update statamic/cms to 5.74.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-54244 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
