Technical details

A permission control vulnerability (CWE-200) exists in the Settings module of Huawei's HarmonyOS and EMUI operating systems. The flaw is characterized by improper enforcement of access controls, which could allow a local attacker to gain unauthorized access to sensitive data. The attack vector is classified as local with a requirement for user interaction (UI:R), suggesting that an attacker might need to trick a user into executing a malicious app or visiting a crafted site to trigger the bypass. Successful exploitation primarily impacts confidentiality. Huawei has addressed this in their July 2026 security update.
