  author: theamanrawat
  severity: medium
  description: WordPress Paytm Payment Gateway plugin through 2.7.0 contains a server-side request forgery vulnerability.

  impact: |
    Unauthenticated attackers can exploit server-side request forgery through the url parameter in the curltest action to make arbitrary HTTP requests from the server, potentially accessing internal network resources and sensitive data.
  remediation: |
    Update to the latest version of the WordPress Paytm Payment Gateway plugin (2.7.0) or apply the vendor-supplied patch.
