No no you do not understand what I am asking.

 

Site/page/$foo

 

$foo can be 1 hundred million things 1 being something correct everything
else is wrong so a user can put in &something=this&that=somethingelse. I am
asking because that get pumped right into cake is there anything you should
do in general (not inflector::slug) to make sure its safe to use since you
cant trust everything coming in. Sure 99% of users will not mess with URLs
but that 1 % who decides to change and mess with things.

 

Should you sanitize $foo so its only [az-09-] do you need to? And no not
because its a slug  but because its safer if you took the & = out of all the
url if you know it should not be there. I am asking in general not in a case
specifi if it's a slug if not forget I even used that word. Think of any url
on your site and think of a evil user typing in something they should not.
Now what would you do to protect the site from what they wrote. That's what
I am asking. Do you need to check the data in the url (and I do not mean
check if it the owner) before you send it to delete / save/ update/ redirect
anything. 

 

Having the site do something or attempt to do something by messing with the
url.

 

Does that make sense or am I just not clear?

Sorry..

 

Not what I was trying to ask. 

Not the if owner delete part of the action.just the passing of variables
thru url.the actual variable. Cake spits out code link/delete/this_slug what
could a user change the "this_slug" variable too that could be harful. What
should you check /clean / for the variable its self. I only used the delete
as a general example so in any case anytime a variable is passed directly to
the controller what should you do if anything to make sure its no code
capable of damage / injection / disruption

in ur case, i will first check, if given id is id for record from some user,
and if is, then delete it, otherwise don't delete it...

When passing an id / slug  thru a url for delete is there any security
precautions to add?

 

Example 

 

Function delete ($id) {

 

$this->Model->deleteAll(array(Model.id => $id, Model.owner =>
$this->Auth->user('id')));

 

}

 

So I pretty much always use deleteAll so its got multiple values of checking
rightful owner / permission to delete but I'm more curious about the passing
of the actual $id since anyone can pass anything they want as an $id if they
want to get smart and mess with your site. So what should you do? Any added
precautions? Sanitize:: the slug / id?

 

Thanks,

Dave
