Are there any security issues I need to worry about jquery-ui-autocomplete working with get array enabled

Hello all

After several weeks of struggling I have finally managed to get the jquery ui autocomplete widget working and reading data from a mysql database however I have had to enable the get array in ci, do I need to be worried about any security problems.

I am using the following

jquery-1.5.1.js

jquery.ui.core.js
jquery.ui.widget.js
jquery.ui.position.js
jquery.ui.autocomplete.js

I am using jquery ui version 1.8.11
CI 2.0.1 with GET array enabled
