CVE-2025-58278 is a vulnerability classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) found in the Gallery app of Huawei's HarmonyOS version 5.0.1. The flaw allows an attacker to bypass identity authentication mechanisms, enabling unauthorized access to sensitive information managed by the Gallery app. The vulnerability is local (AV:L), requires low attack complexity (AC:L), and no privileges or user interaction (PR:N/UI:N) are needed, making it easier to exploit by anyone with physical or local access to the device. The impact is limited to confidentiality (C:H), with no effect on integrity or availability. Although no public exploits are currently known, the vulnerability poses a risk of sensitive data leakage, which could include personal photos, metadata, or other private content stored or processed by the Gallery app. The absence of patches at the time of publication necessitates proactive mitigation. Given Huawei's significant market share in mobile devices in Europe, especially in consumer and some enterprise environments, this vulnerability could affect a broad user base. The technical details indicate the vulnerability was reserved in late August 2025 and published in October 2025, suggesting a recent discovery. Organizations relying on Huawei HarmonyOS devices should be aware of this issue and prepare for patch deployment.

The primary impact of CVE-2025-58278 is the unauthorized exposure of sensitive information, which can lead to privacy violations, data leakage, and potential compliance issues under European data protection regulations such as GDPR. For European organizations, especially those in sectors like finance, healthcare, and government that handle sensitive personal or corporate data, this vulnerability could result in reputational damage and legal consequences if exploited. The local attack vector means that physical or local access to devices is required, which somewhat limits remote exploitation but raises concerns for lost, stolen, or shared devices within organizations. The confidentiality breach could also facilitate further social engineering or targeted attacks if sensitive personal or corporate information is disclosed. The lack of impact on integrity and availability reduces the risk of system disruption but does not diminish the seriousness of data exposure. The medium severity rating reflects this balance of impact and exploitability.

1. Monitor Huawei's official security advisories closely and apply patches for HarmonyOS 5.0.1 Gallery app as soon as they become available. 2. Implement strict physical security controls to prevent unauthorized local access to devices, including device locking policies and secure storage. 3. Enforce strong device authentication mechanisms (PIN, biometric) to reduce the risk of unauthorized local access. 4. Limit the use of Huawei HarmonyOS devices in sensitive environments until patches are applied. 5. Conduct regular audits of device usage and access logs to detect suspicious activity indicative of exploitation attempts. 6. Educate users about the risks of leaving devices unattended or lending them to untrusted individuals. 7. Consider deploying endpoint detection and response (EDR) solutions capable of monitoring local access anomalies on mobile devices. 8. For organizations with BYOD policies, enforce compliance checks ensuring devices are updated and secured.
