Indeed, it probably is, but hopefully the results of that are not then echoed out to the browser without running htmlspecialchars() etc on them... If they are (which is the root of this "security problem") then that is the fault of the idiot who wrote the code, not PHP. You can only protect users from their own stupidity to a certain degree...
