Advisory

Source description from Wordfence Intelligence, credited to Duc Manh.

The Error Log Viewer by BestWebSoft plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.1.6 via the rrrlgvwr_get_file function. This makes it possible for authenticated attackers, with Administrator-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.
