Critical Elementor Pro Vulnerability Exposes 10M+ WordPress Sites to Remote Code Execution
A critical vulnerability (CVE-2026-32475) in Elementor Pro WordPress plugin versions before 4.2.2 allows unauthenticated attackers to upload executable PHP files for remote code execution. The flaw stems from inconsistent file validation logic in the File Upload module, where empty filename entries are handled differently by validation and processing loops. Attackers can exploit this by crafting multipart uploads with empty first entries followed by malicious PHP payloads, bypassing validation and uploading executable files to public directories. With over 10 million WordPress installations using Elementor, this vulnerability poses significant risk to websites using Elementor Pro forms with file upload functionality enabled. This incident highlights the growing trend of supply chain vulnerabilities targeting popular WordPress plugins and website builders. As organizations increasingly rely on third-party components for web development, plugin vulnerabilities have become a primary attack vector for gaining initial access to web infrastructure and conducting broader network compromises.
