id: CVE-2023-37999

info:
  name: HT Mega – Absolute Addons for Elementor <= 2.2.0 - Missing Authorization to Privilege Escalation
  author: daffainfo
  severity: critical
  description: |
    The HT Mega plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 2.2.0. This is due to missing validation of the reg_role parameter on the htmega_ajax_register function. This makes it possible for unauthenticated attackers to create administrator accounts.
  impact: |
    Attackers can escalate privileges, gaining unauthorized access to restricted functionalities or data.
  remediation: |
    Update to the latest version of HT Mega to address the privilege management issue.
