CVE-2022-0651: WordPress Plugin WP Statistics <= 13.1.5 - SQL Injection

id: CVE-2022-0651

info:
  name: WordPress Plugin WP Statistics <= 13.1.5 - SQL Injection
  author: theamanrawat
  severity: high
  description: |
    The WP Statistics WordPress plugin is vulnerable to SQL Injection due to insufficient escaping and parameterization of the current_page_type parameter found in the ~/includes/class-wp-statistics-hits.php file which allows attackers without authentication to inject arbitrary SQL queries to obtain sensitive information, in versions up to and including 13.1.5.
  remediation: Update wp-statistics plugin to version 13.1.6, or newer.
