Description

The Livemesh Addons for Elementor plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 9.0. This is due to insufficient sanitization of the template name parameter in the `lae_get_template_part()` function, which uses an inadequate `str_replace()` approach that can be bypassed using recursive directory traversal patterns. This makes it possible for authenticated attackers, with Contributor-level access and above, to include and execute arbitrary files on the server, allowing the attacker to include and execute local files via the widget's template parameter granted they can trick an administrator into performing an action or install Elementor.
