Elementor < 3.19.1 - Authenticated(Contributor+) Arbitrary File Deletion and PHAR Deserialization

Description

The Elementor Website Builder – More than Just a Page Builder plugin for WordPress is vulnerable to arbitrary file deletions and PHAR deserialization in version up to, and including 3.19.0. This is due to the plugin not providing sufficient path validation on the 'tmp_name' parameter . This makes it possible for authenticated attackers, with contributor-level access and above, to delete arbitrary files and inject PHP Objects through the use of a phar wrapper, both of which can lead to remote code execution.
