CVE-2026-26214
📋 TL;DR
This vulnerability in the Galaxy FDS Android SDK disables TLS hostname verification, allowing man-in-the-middle attackers to intercept and modify communications between Android apps and Xiaomi's cloud storage service. All applications using SDK version 3.0.8 or earlier with default HTTPS settings are affected, potentially exposing authentication credentials and file data. The SDK has reached end-of-life status, complicating remediation.

⚠️ Risk & Real-World Impact
Worst Case
Attackers intercept authentication tokens and file uploads/downloads, gaining unauthorized access to cloud storage accounts and sensitive user data.
Likely Case
Man-in-the-middle attackers in controlled networks (public Wi-Fi, compromised routers) intercept API calls and file transfers, potentially stealing credentials and modifying data.
If Mitigated
With proper network segmentation and certificate pinning, impact is limited to specific network segments where attackers have positioning.
🎯 Exploit Status
Exploitation requires network positioning for MITM attacks. No public exploit code needed as this is a configuration vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: None
Vendor Advisory: https://github.com/XiaoMi/galaxy-fds-sdk-android
Restart Required: No
Instructions:
1. Migrate to alternative SDK or implement custom TLS verification. 2. Fork and patch the SDK source code to enable proper hostname verification. 3. Rebuild and redeploy affected applications.
🔧 Temporary Workarounds
Implement Certificate Pinning
androidAdd certificate pinning to the application to validate server certificates against known good certificates.
Network Segmentation
allRestrict affected applications to trusted networks only, avoiding public or untrusted Wi-Fi.
🧯 If You Can't Patch
- Disable the SDK's HTTPS functionality and use alternative secure communication methods
- Implement application-level encryption for all data transmitted through the SDK
🔍 How to Verify
Check if Vulnerable:
Check Android application dependencies for galaxy-fds-sdk-android version ≤3.0.8. Review source code for SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER usage.Check Version:
Check build.gradle or dependencies for 'com.xiaomi:galaxy-fds-sdk-android:3.0.8' or earlierVerify Fix Applied:
Verify that hostname verification is enabled in TLS configuration and test with invalid certificates to ensure connections fail.📡 Detection & Monitoring
Log Indicators:
- TLS handshake failures with certificate validation errors
- Unexpected API call patterns to FDS endpoints
Network Indicators:
- Unencrypted traffic to FDS endpoints
