Error Log Viewer By WP Guru < 1.0.4 - Missing Authorization to Unauthenticated Arbitrary File Read

Description

The Error Log Viewer By WP Guru plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 1.0.1.3 via the wp_ajax_nopriv_elvwp_log_download AJAX action. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information.
