Name of the Vulnerable Software and Affected Versions Android versions prior to the fixed version

Description The issue is related to a permissions bypass in the ShortcutService.java, specifically in the isRequestPinItemSupported function. This could lead to a cross-user leak of packages, resulting in local information disclosure without requiring additional execution privileges. User interaction is not necessary for exploitation.

Recommendations For Android versions prior to the fixed version, consider restricting access to the ShortcutService.java until a patch is available. As a temporary workaround, disabling the isRequestPinItemSupported function may help minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
