CVE-2025-54615 is a vulnerability identified in Huawei's HarmonyOS, specifically affecting versions 5.0.1 and 5.1.0. The vulnerability is categorized under CWE-200, which refers to the Exposure of Sensitive Information to an Unauthorized Actor. The issue resides in the media library module of HarmonyOS, where insufficient protection mechanisms allow unauthorized access to sensitive data. According to the CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), the vulnerability can be exploited locally (AV:L) with low attack complexity (AC:L), does not require privileges (PR:N) or user interaction (UI:N), and impacts confidentiality (C:H) without affecting integrity or availability. This means an attacker with local access to the device can extract sensitive information from the media library without needing elevated permissions or user involvement. The vulnerability does not appear to have known exploits in the wild as of the publication date (August 6, 2025), and no patches have been linked yet. The exposure of sensitive information could include personal media files, metadata, or other confidential data stored or processed by the media library component, potentially leading to privacy violations or information leakage. Given the local attack vector, exploitation would require physical or local network access to the device, limiting the attack surface but still posing a significant risk if devices are compromised or accessed by malicious insiders or attackers with local presence.

For European organizations, the impact of CVE-2025-54615 depends largely on the deployment of Huawei HarmonyOS devices within their environment. If HarmonyOS-powered devices are used for corporate communications, media handling, or data storage, this vulnerability could lead to unauthorized disclosure of sensitive corporate or personal information. The confidentiality breach could expose intellectual property, personal employee data, or sensitive multimedia content. This is particularly critical for sectors with stringent data protection requirements such as finance, healthcare, and government institutions under GDPR regulations. The local attack vector reduces the risk of remote exploitation but increases the importance of physical device security and endpoint protection. Organizations with employees using HarmonyOS devices in office or remote environments may face insider threats or risks from lost/stolen devices. The absence of known exploits in the wild provides a window for proactive mitigation, but the medium severity rating indicates that the threat should be taken seriously to prevent potential data leaks.

1. Implement strict physical security controls to prevent unauthorized local access to HarmonyOS devices, including device lock policies and secure storage. 2. Enforce endpoint security solutions that monitor and restrict local access to sensitive media files and system components. 3. Educate users about the risks of leaving devices unattended or lending them to untrusted individuals. 4. Monitor for unusual local access patterns or attempts to access media library data. 5. Maintain an inventory of HarmonyOS devices and restrict their use in sensitive environments until patches or updates are available. 6. Engage with Huawei or authorized vendors to obtain security patches or updates addressing this vulnerability as soon as they are released. 7. Consider network segmentation and device management policies that limit the exposure of HarmonyOS devices within corporate networks. 8. Use data encryption for sensitive media files to add an additional layer of protection against unauthorized local access.
