Summary

Craft CMS is a content management system. In versions on the 4.x branch through 4.17.8 and the 5.x branch through 5.9.14, the resource-js endpoint allows unauthenticated requests to proxy remote JavaScript resources. When trustedHosts is not explicitly restricted, the application trusts the client-supplied Host header, allowing an attacker to control the derived baseUrl and leading to SSRF.

Risk Assessment

An attacker can exploit the SSRF vulnerability to make arbitrary HTTP requests from the server, potentially accessing internal resources. This may compromise infrastructure security.

Recommendation

Update Craft CMS to version 4.17.9 or 5.9.15, which patch this issue.

Original NVD description (English source)

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 `resource-js` endpoint in Craft CMS allows unauthenticated requests to proxy remote JavaScript resources. When `trustedHosts` is not explicitly restricted (default configuration), the application trusts the client-supplied Host header. This allows an attacker to control the derived `baseUrl`, which is used in prefix validation inside `actionResourceJs()`. 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.
