CVE-2025-27563

Local information disclosure via permission retrieval bypass

Published Jun 8, 2025 · Updated Jun 9, 2025

Improper permission preservation in OpenHarmony 5.0.1 through 5.0.3 allows local users to disclose sensitive information. The security_access_token component fails to preserve intended restrictions during a permission-retrieval operation; the affected function and data path are undisclosed. Exploitation requires low-privileged local access, and the published assessments report no integrity or availability impact.
