Summary

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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
