db. In turn this can cause SQL query errors such as:

UPDATE cp_users SET lastaction=NOW() WHERE nick='<BODY 
BACKGROUND="javascript:alert('XSS')">'
You have an error in your SQL syntax. Check the manual that corresponds to your 
MySQL server version for the right syntax to use near 'XSS')">'' at line 3
