Hey guys, I waswondering, I am finishing up a membership site in which i would like to give people the opportunity to put youtube videos and other embed coded things on a wall on their profiles. Am I leaving myself open to anything malicious. I see it all over the place and most of these social networks have this feature but i wanted to get some info on it. Thanks in advance.

you would probably need to have a list of approved tags, and approved attributes so there would be no javascript executing on your pages, or anything malicious....you would need to filter through what their trying to embed....just my thoughts....:-P i might be wrong hahahah

yea anytime you allow users to do things on a site your opening the door  you need to filter what you allow

 

for example allowing youtube videos fine in most cases but not filtering the embed tag i can create some pretty horrible flash  that pulls php javascript and all kinds of other things into the picture
