This is due to the encryption for the email attachments being disabled and penetrable by threats on the web. Kurtz has shared his discovery on Apple and despite the company acknowledging it, there is no word on when the fix will be released.
The security flaw certainly contradicts to Apple’s bold claims where the email attachments are encrypted and safe for sending. The good news is that the security loophole is only with the email attachments. Aside from that, everything looks secured.
At the moment, Apple is looking for a fix to the matter and it will be ready in the next software update.
