Critical Privilege Escalation and File Upload Vulnerabilities in King Addons for Elementor

More than 10,000 WordPress sites using the King Addons for Elementor plugin are at risk of total site compromise due to two critical vulnerabilities. The first flaw, an unauthenticated privilege escalation (CVE-2025-8489), allows attackers to register new accounts with administrator privileges by exploiting improper role restrictions in plugin versions 24.12.92 through 51.1.14. The second vulnerability, an unauthenticated arbitrary file upload (CVE-2025-6327), enables attackers to inject malicious files into various directories by abusing an AJAX handler's exposed nonce, further increasing the risk of site takeover.

Security researchers from Patchstack and Wordfence have confirmed that both vulnerabilities are remotely exploitable and require no authentication, making them highly attractive targets for threat actors. Site administrators are strongly urged to update to patched versions of the plugin, which now include a role allowlist, improved input sanitization for account creation, and stricter file type validation in the upload handler. Immediate patching is recommended to prevent exploitation and potential full compromise of affected WordPress sites.
