From official site:
Version 2.9.2 contains some security fixes (see Security on phpmyadmin.net) and other fixes.
From me: The vulnerability is quite serious so I suggest upgrading ASAP.

XSS and Path Disclosure vulnerabilities
We received an advisory from Laurent Gaffié and we wish to thank him for his work.
It was possible to trigger these attacks on db_create.php and index.php.
We consider these vulnerabilities to be serious.
Probably all versions to 220.127.116.11.
Upgrade to phpMyAdmin 2.9.2 or newer.
