Existía un problema de Cross-Site Scripting (XSS) en Safari. Este problema se abordó con una validación de URL mejorada. El problema afectaba a iOS en versiones anteriores a la 12, tvOS en versiones anteriores a la 12, Safari en versiones anteriores a la 12, iTunes para Windows en versiones anteriores a la 12.9 y iCloud para Windows en versiones anteriores a la 7.7.

This vulnerability allows remote attackers to bypass the same-origin policy on vulnerable installations of Apple Safari. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file and execute a user gesture within the rendered HTML.
The specific flaw exists within the handling of subframes. The issue lies in the ability to execute arbitrary JavaScript without preserving the original origin. An attacker can leverage this vulnerability to execute script in the context of a different domain.
