The Last.fm desktop app (Last.fm Scrobbler) through 2.1.39 on macOS makes HTTP requests that include an API key without the use of SSL/TLS. Although there is an Enable SSL option, it is disabled by default, and cleartext requests are made as soon as the app starts.
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
