According to ZecOps, the vulnerabilities have existed since iOS 6, a version released in 2012. The company reported its findings to Apple in February and March, and notified the tech giant of attacks exploiting the flaws. The vendor has patched the weaknesses in iOS 13.4.5 beta. Other email apps for iOS, such as Gmail and Outlook, do not seem to be impacted so using these applications is recommended for preventing attacks until Apple rolls out the patch to all users.
