info:
  name: WordPress Embed Swagger <=1.0.0 - Cross-Site Scripting
  author: edoardottt
  severity: medium
  description: |
    WordPress Embed Swagger plugin 1.0.0 and prior contains a reflected cross-site scripting vulnerability due to insufficient escaping/sanitization and validation via the url parameter found in the ~/swagger-iframe.php file, which allows attackers to inject arbitrary web scripts onto the page.
  impact: |
    Successful exploitation of this vulnerability could allow an attacker to execute arbitrary JavaScript code in the context of the victim's browser, potentially leading to session hijacking, defacement, or theft of sensitive information.
  remediation: |
    Update to the latest version of the WordPress Embed Swagger plugin (1.0.0) or apply a patch provided by the vendor.
