  description: |
    WordPress XML Sitemap Generator for Google plugin before 2.0.4 contains a cross-site scripting vulnerability that can lead to remote code execution. It does not validate a parameter which can be set to an arbitrary value, thus causing cross-site scripting via error message or remote code execution if allow_url_include is turned on.
  impact: |
    Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code on the affected system or inject malicious scripts into web pages viewed by users.
  remediation: |
