CVE-2025-54618

Adjacent clipboard-data disclosure

Published Aug 6, 2025 · Updated Aug 6, 2025

Permission control failure in HarmonyOS 5.0.1 and 5.1.0 allows remote authenticated users to read distributed clipboard data. Huawei identifies the distributed clipboard module but has not published the faulty permission operation or the input that reaches it. Exploitation requires low privileges and adjacent-network access; the documented consequence is disclosure only, with no integrity or availability impact.
