CVE-2025-4102Network attack vector

Arbitrary file upload via unvalidated icon-set types

Published Jun 20, 2025 · Updated Apr 8, 2026

Arbitrary file upload in Beaver Builder 2.9.1 and earlier allows remote authenticated users with Administrator access to upload server files. The save_enabled_icons function accepts attacker-supplied icon-set files without validating their types, allowing executable PHP content to reach the WordPress server. Administrator privileges are required; server-side execution depends on the uploaded content being reachable and executable, while arbitrary file placement is the established impact.
