Advisory

Source description from Wordfence Intelligence, credited to apple502j.

The Error Log Viewer WordPress plugin through 1.1.1 does not perform nonce check when deleting a log file and does not have path traversal prevention, which could allow attackers to make a logged in admin delete arbitrary text files on the web server.
