Statamic: Missing file upload validation on frontend forms allows uploading disallowed file types

EPSS Percentile

Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.74.3 and 6.24.2, public frontend forms did not enforce the file upload restrictions that the Control Panel enforces, so an unauthenticated visitor could upload file types an administrator had intended to disallow through a form's assets or files field, and for assets fields, files could be stored on a public, web-accessible disk, though the application's global upload allowlist still blocked executable types such as .php and .html. This issue is fixed in versions 5.74.3 and 6.24.2.
