CVE-2025-46587
📋 TL;DR
A permission control vulnerability in Huawei's media library module allows unauthorized access to protected media files. This affects Huawei devices and services using the vulnerable media library component, potentially exposing sensitive user media content.
💻 Affected Systems
- Huawei devices with media library functionality
📦 What is this software?
Harmonyos by Huawei
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain unauthorized access to private media files including photos, videos, and documents stored in the media library, leading to data breach and privacy violations.
Likely Case
Local attackers or malicious apps bypass permission checks to access media files they shouldn't have permission to view, compromising user privacy.
If Mitigated
With proper access controls and isolation, impact is limited to specific media library instances with minimal data exposure.
🎯 Exploit Status
Exploitation likely requires some level of access to the device or application context. No public exploit code available at this time.
🛠️ Fix & Mitigation
