Further worse news is that an attack against Apple's latest version of iOS 13.x can occur while the app is open in the background and does not require interaction by the user to execute the code and compromise your device.
Users who rely on Mail.app to handle emails should stop using the app until Apple releases the official 13.4.5 update to patch the vulnerability.
Since the attack can still occur without user intervention, users should delete the Mail app from their iOS devices by tapping and holding the app's icon until the context menu appears, then select Delete App.
While the steps listed above for personal devices apply to company-owned devices as well, many companies use an MDM solution to manage their iOS devices remotely.
One caveat to this method is that users will only be able to reinstall the app if they have access to the App Store.
