The CLEVER - HTML5 Radio Player With History - Shoutcast and Icecast - Elementor Widget Addon plugin for WordPress is vulnerable to arbitrary file read due to insufficient file path validation in the 'history.php' file in all versions up to, and including, 2.4. This makes it possible for unauthenticated attackers to read arbitrary files on the affected site's server, which may contain sensitive information including database credentials. The vulnerability was partially patched in version 2.4.
The product allows user input to control or influence paths or file names that are used in filesystem operations.
