Reporting a Vulnerability

We take the security of Radio seriously. If you believe you have found a security vulnerability, please report it via GitHub Issues before disclosing it publicly.

Create a new security issue: GitHub Issues — Security. We will respond within 48 hours acknowledging your report and work with you to understand and address the issue.

Include in your report:

  • Description of the vulnerability
  • Steps to reproduce
  • Affected versions (if known)
  • Potential impact
  • Any suggested fixes (optional)

We appreciate responsible disclosure and will credit researchers who report valid security issues (unless you prefer to remain anonymous).

Supported Versions

Version Supported
> 14.5 ✅
< 14.5 ❌

Only the latest stable release receives security updates. Users on older versions are encouraged to update.

Security Considerations

Network Security

Radio streams audio over the internet and connects to the radio-browser.info API for station search. The app allows cleartext HTTP traffic for radio stream compatibility (required for many legacy radio stations).

Data Collection

  • Station data (names, images, stream URLs) is fetched from radio-browser.info's public API
  • Station lists are stored locally on the device only
  • No personal data is collected or transmitted to michatec servers
  • Usage data is not collected

Permissions

Radio requests only the permissions necessary for core functionality:

  • INTERNET — stream radio and fetch station metadata
  • ACCESS_NETWORK_STATE — detect connectivity changes
  • FOREGROUND_SERVICE_MEDIA_PLAYBACK — maintain playback when app is backgrounded
  • WAKE_LOCK — prevent device from sleeping during playback

Third-Party Dependencies

Radio uses several third-party libraries. Security issues in dependencies are monitored via Renovate bot for updates. Key dependencies include:

  • AndroidX Media3 / ExoPlayer (media playback)
  • Google Cast SDK (Chromecast support)
  • Volley (HTTP requests)

File Handling

The app can import M3U/PLS playlist files from external sources. Files are processed locally and stream URLs are validated before playback. Station images are downloaded from radio-browser.info and cached locally.

Security Update Process

Security patches are delivered via normal app update channels (GitHub Releases, automated update notifications). Critical vulnerabilities may trigger an out-of-band security update.
