CVE-2026-49302

Local notification-service data exposure

Published Aug 17, 2026 · Updated Aug 18, 2026

Information disclosure in Huawei HarmonyOS 6.1.0 allows local users to read notification-service data via improper permission control. Huawei and NVD identify the notification service module as the affected locus, but public records do not disclose which interface or code path fails to enforce permissions on untrusted access requests. Reachability is local with no privileges or user interaction per the published CVSS vector, and the reported impact is limited to confidentiality of notification-service data.
