Information exposure in Huawei HarmonyOS 5.0.0 allows local users to access service data through the UIExtension module. Huawei identifies a cross-process screen-stack flaw in the UIExtension module but does not disclose the operation that mishandles screen data. Local execution with no prior privileges or user interaction is required, and the documented consequence is limited to confidentiality.
