{"apiVersion":"1.0","identifier":"CVE-2026-41130","description":"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.","publishedAt":"2026-04-22T00:16:28","lastModifiedAt":null,"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-41130","cvssScore":5.5,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.0026,"riskScore":0.56,"affectedProduct":"Craft CMS","affectedVersions":"<4.17.9, <5.9.15","vulnerabilityType":"Core software","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-41130","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-41130","en":"https://www.redsauce.net/en/cves/CVE-2026-41130","fr":"https://www.redsauce.net/fr/cves/CVE-2026-41130","pt":"https://www.redsauce.net/pt/cves/CVE-2026-41130","de":"https://www.redsauce.net/de/cves/CVE-2026-41130","sk":"https://www.redsauce.net/sk/cves/CVE-2026-41130","el":"https://www.redsauce.net/el/cves/CVE-2026-41130"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-41130"}}
