A simple Skype exploit can reveal any user's remote and local IP address.
A blog post by skype-open-source runs through the process of obtaining a user's IP address. Essentially, all a person has to do is start the process of adding a contact with a specific user name. Instead of sending a contact confirmation, the person can click on the information card to obtain the IP address.
The process only works if the other user is online. The only method of protecting against this is to log off of Skype when not in use, or using a virtual private network to hide the IP address, according to ghacks.
CNET contacted Skype for comment. We'll update the story when we get more information.
