## Description

An attacker can exploit phpMyAdmin before 4.8.4 to leak the contents of a
local file because of an error in the transformation feature. The attacker
must have access to the phpMyAdmin Configuration Storage tables, although
these can easily be created in any database to which the attacker has
access. An attacker must have valid credentials to log in to phpMyAdmin;
this vulnerability does not allow an attacker to circumvent the login
system.

### From the Ubuntu Security Team

It was discovered that there was a bug in the way phpMyAdmin handles the
phpMyAdmin Configuration Storage tables. An authenticated attacker could use
this vulnerability to cause phpmyAdmin to leak sensitive files.
