info:
  name: WordPress W3 Total Cache <2.1.5 - Cross-Site Scripting
  author: theamanrawat
  severity: medium
  description: |
    WordPress W3 Total Cache plugin before 2.1.5 is susceptible to cross-site scripting via the extension parameter in the Extensions dashboard, when the setting 'Anonymously track usage to improve product quality' is enabled. The parameter is output in a JavaScript context without proper escaping. This can allow an attacker, who can convince an authenticated admin into clicking a link, to run malicious JavaScript within the user's web browser, which could lead to full site compromise.
  remediation: Fixed in version 2.1.5.
