Summary

In specific versions of Apple's iOS, tvOS, and OS X El Capitan, a vulnerability existed where the proxy authentication mechanism incorrectly indicated that credentials were securely transmitted to HTTP proxies. This security flaw could potentially lead to unauthorized access and compromise user data by misrepresenting the security of credential transmission. Apple addressed this issue in subsequent updates by implementing improved notifications to make users aware of the potential risks associated with proxy authentication.
