Our application makes use of various tracking pixels and the way the information is sent to the third party tracker is by using the IMAGE tag and appending the information at the end of the url.(IMGAGE SRC="https://abc.com/a.php?username=bob&cost=22).
The new 3rd party tracking pixel wants the above information in an IFRAME tag as shown below IFRAME SRC="https://abc.com/a.php?username=bob&cost=22 IFRAME
Is there any security risk using the IFRAME ?
