CVE-2023-48701: Cross-site Scripting via uploaded assets

November 22, 2023

Statamic CMS is a Laravel and Git powered content management system (CMS). Prior to versions 3.4.15 an 4.36.0, HTML files crafted to look like images may be uploaded regardless of mime validation. This is only applicable on front-end forms using the “Forms” feature containing an assets field, or within the control panel which requires authentication. This issue has been patched on 3.4.15 and 4.36.0.
