CVE-2026-49301

Unauthorized gallery data disclosure to local users

Published Aug 17, 2026 · Updated Aug 17, 2026

Permission control vulnerability in the Gallery module in Huawei EMUI and HarmonyOS allows local users to read data via unauthorized access. Huawei has not published the flawed code path or the specific permission check that the Gallery module performs incorrectly, so the public record does not identify a function, API, or request path. Published scoring treats the flaw as locally reachable without prior privileges, and the disclosed impact is limited to unauthorized disclosure rather than modification or service interruption.
