SSRF in Statamic Cms
CVE-2026-28423
Statmatic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.11 and 6.4.0, when Glide image manipulation is used in insecure mode (which is not the default), the image proxy can be abused by an unauthenticated user to make the server send HTTP requests to arbitrary URLs—either via the URL directly or via the watermark feature. That can allow access to internal services, cloud metadata endpoints, and other hosts reachable from the server. This has been fixed in 5.73.11 and 6.4.0.
