Are you currently using Skype for iPhone?, either you better remove it soon as you see this or just leave it without using it, since there’s a cross-site scripting vulnerability revealed in the “Chat Message” window in version 3.0.1 and earlier.
Heres what the researcher who found the vulnerability got to say :
File system access is partially mitigated by the iOS Application sandbox that Apple has implemented, preventing an attacker from accessing certain sensitive files. However, every iOS application has access to the users AddressBook, and Skype is no exception.
Also Skype told with TechCrunch that they are aware of the security issue and are working on a fix for it:
“We are working hard to fix this reported issue in our next planned release which we hope to roll out imminently. In the meantime we always recommend people exercise caution in only accepting friend requests from people they know and practice common sense internet security as always.”
Below is the video embedded which shows this in action:
