Does not affect 2.0.6.
This code prevents it:
function get_userdata($user, $force_str = false)
{
global $db;
if (intval($user) == 0 || $force_str)
{
$user = trim(htmlspecialchars($user));
$user = substr(str_replace("\\'", "'", $user), 0, 25);
$user = str_replace("'", "\\'", $user);
}
else
{
$user = intval($user);
}
