According to the CVSS score, this vulnerability has Scope: Changed (S:C). What does this mean?
A CVSS Scope change (S:C) means that successful exploitation of this vulnerability allows an attacker to access resources outside the original security boundary of the vulnerable component. In this case, the vulnerable code runs within a restricted AppContainer environment, and exploitation could allow an attacker to access sensitive user data outside of that sandbox. Although this does not provide full system control, it represents a break out of the intended isolation boundary.
