Possible Fixes: The usage of htmlspeacialchars(), mysql_escape_string(), mysql_real_escape_string() and other functions for input
validation before passing user input to the mysql database, or before echoing data on the screen, would solve these problems.

Are you sure, is that sql injection in 0.760=RC3?

Code "article.php":
if ((empty($sid) && empty($tid)) ||
(!is_numeric($sid) && !is_numeric($tid))) {
include 'header.php';
echo _MODARGSERROR;
include 'footer.php';
exit;
}

So exit; ;] Bug don't work in 0.760-RC3. And in 0.750 exist path d.
