We take security seriously. If you believe you have found a security vulnerability in Universal Device Toolkit, please report it responsibly through our coordinated disclosure process.

1. Do NOT open a public GitHub issue
2. Do NOT disclose the vulnerability publicly
3. Do send a detailed report to: 3992237161@qq.com

Your report should include:

• Description of the vulnerability
• Steps to reproduce the issue
• Affected components or versions
• Potential impact assessment
• Suggested remediation (if any)

1. No Telemetry: UDT contains no data collection or tracking
2. No Background Services: Application only runs when actively used
3. Local-Only Operation: No cloud dependencies or remote servers
4. Privacy-First Design: User data stays on the user's machine

UDT does NOT collect:

• ❌ Usage statistics
• ❌ Hardware identifiers
• ❌ Software inventory
• ❌ User behavior patterns
• ❌ Personal information

The plugin system was retired in 6.1. The shipping Electron renderer runs sandboxed and reaches privileged operations only through the preload bridge. Unexpected top-level navigation and new windows are denied. Main-process handlers validate the current main frame, restrict external URLs to HTTP(S), and reject executable or script paths supplied by the renderer.

• NuGet Packages: Regularly updated
• Security Scanning: GitHub Dependabot enabled
• Vulnerability Alerts: Automatic notifications
• License Compliance: Review of all dependencies

1. Download from Official Sources

   • GitHub Releases only
   • Verify checksum when possible
   • Check digital signature

2. Permission Management

   • Review requested permissions
   • Run with minimal privileges
   • Disable unused features

3. Update Safety

   • Install releases from the official repository
   • Keep checksum manifests with downloaded installers
   • Do not bypass operating-system signature warnings

1. Code Security

   • All input validation
   • No hardcoded credentials
   • Secure string handling
   • FxCop analyzers enabled

2. Dependency Updates

   • Regular dependency audits
   • Automated PRs for updates
   • Security patches prioritized

3. Testing Requirements

   • Security tests for hardware interfaces
   • Electron sandbox and IPC boundary tests
   • Path and update-integrity tests

Some features require elevated permissions:

• WMI access for power management
• ACPI communication for firmware
• USB/HID access for RGB control

These are necessary for hardware control but increase the application's trust boundary.

Renderer compromise is treated as a trust-boundary failure, not as permission to execute arbitrary local programs. Keep the preload API narrow, validate the calling frame in privileged IPC handlers, and do not re-enable Node.js integration or disable the Chromium sandbox.

The update mechanism:

• Uses HTTPS for all downloads
• Verifies the downloaded payload against a SHA-256 release digest or manifest
• Launches only the installer path produced by the verified downloader
• Allows manual update rejection

• OWASP: Application security guidelines followed
• CWE: Common Weakness Enumeration awareness
• NIST: Cybersecurity framework considerations

• GDPR: No personal data collection
• CCPA: No data sale or sharing
• LGPD: No international data transfers

We thank the security research community for helping us keep Universal Device Toolkit secure. Responsible disclosure allows us to address vulnerabilities before they affect users.

• Watch GitHub Releases for updates
• Enable auto-updates in settings
• Follow project announcements

Security updates are:

• Marked clearly in release notes
• Prioritized over feature releases
• Documented with CVE references (if applicable)
