CVE-2026-49307

Sensitive service-data exposure to local attackers

Published Aug 17, 2026 · Updated Aug 17, 2026

Information disclosure in the multi-mode input module in Huawei HarmonyOS 6.1.0 allows local attackers to read protected service data. Huawei has disclosed only that the module contains a permission-control flaw; the specific code path and the incorrect permission check or access-control operation have not been made public. Reachability is local with no authentication or user interaction listed, and the published impact is limited to confidentiality rather than data modification or service interruption.
