Security policy

Supported versions

Atrium is pre-1.0. Only the latest commit on main is supported.

Reporting a vulnerability

Please report security issues privately - do not open a public issue.

  • Email: see the maintainer's GitHub profile.
  • Or use GitHub's "Report a vulnerability" private disclosure flow on the repository.

Please include:

  • Affected version / commit
  • A clear description of the issue and its impact
  • Reproduction steps or a proof of concept
  • Any suggested mitigation

We aim to acknowledge within 72 hours and to land a fix or workaround within 30 days for high-severity issues.

Threat model

Atrium stores API keys for self-hosted services (Sonarr, Radarr, qBit, etc.) in the Android Keystore via flutter_secure_storage. Optional biometric unlock can gate access. Non-secret configuration lives in plain Hive boxes excluded from Android auto-backup.

We are not in scope for:

  • Compromise of the upstream services themselves (report those upstream)
  • Attacks requiring an already-rooted device with debug access
  • Vulnerabilities in third-party plugins not maintained by this project

There aren't any published security advisories
