CVE-2025-26691

Local information disclosure via telephony permission bypass

Published Jun 8, 2025 · Updated Jun 9, 2025

Permission bypass in OpenHarmony 5.0.1 through 5.0.3 allows local users to disclose sensitive information through telephony_call_manager. OpenHarmony identifies telephony_call_manager as the affected repository but has not published the permission check or data-access operation implemented incorrectly. Low-privilege local access is required, no user interaction is needed, and the reported consequence is limited to confidentiality.
