  name: FormCraft3 <= 3.9.15 - Server-Side Request Forgery
  author: DhiyaneshDk
  severity: high
  description: |
    Unauthenticated Server Side Request Forgery (SSRF) in FormCraft <= 3.9.15 versions.
  impact: |
    An unauthenticated attacker can force the server to make HTTP requests to arbitrary internal or external URLs, potentially accessing cloud metadata services (AWS/GCP/Azure), internal network services, and sensitive data.
  remediation: |
    Update FormCraft3 to version 3.9.16 or later which adds nonce verification and authentication checks to the formcraft3_get AJAX endpoint.
