Craft CMS is a content management system (CMS). In versions on the 4.x branch through 4.17.8 and the 5.x branch through 5.9.14, the endpoint in Craft CMS allows unauthenticated requests to proxy remote JavaScript resources. When is not explicitly restricted (default configuration), the application trusts the client-supplied Host header. This allows an attacker to control the derived , which is used in prefix validation inside . By supplying a malicious Host header, the attacker can make the server issue arbitrary HTTP requests, leading to Server-Side Request Forgery (SSRF). Versions 4.17.9 and 5.9.15 patch the issue.
