## Reporting a Vulnerability

**Please do not open public issues for security vulnerabilities.**

Use [GitHub's private vulnerability reporting](https://github.com/OpenWhispr/openwhispr/security/advisories/new)
to submit a report. You can also email security@openwhispr.com.

We will acknowledge your report within **48 hours** and aim to release a fix
within **7 days** for critical issues.

## Scope

The following are in scope:

- Remote code execution via crafted audio files or transcription output
- Privilege escalation through native binaries (key listeners, paste helpers)
- Credential exposure (API keys, OAuth tokens, database credentials)
- Cross-site scripting (XSS) in the Electron renderer
- Insecure IPC between main and renderer processes
- Supply chain attacks via dependencies or native compilation

Out of scope:

- Issues requiring physical access to an already-unlocked machine
- Denial of service against the local application
- Social engineering

## Security Model

- **Local-first audio processing** — Audio is transcribed on-device using
  whisper.cpp or nvidia parakeet. Recordings are not sent to external servers unless explicitly
  configured by the user.
- **Credential storage** — API keys provided by users (BYOK) and enterprise
  cloud credentials (AWS, Azure, Vertex) are encrypted at rest using
  Electron's `safeStorage` API, which delegates to the OS keychain (Keychain
  on macOS, DPAPI on Windows, libsecret on Linux). Encrypted blobs are stored
  under `userData/secure-keys/`. Non-secret preferences (regions, endpoints,
  hotkeys, flags) continue to live in `.env`. On Linux systems without a
  keyring, secrets fall back to plaintext to match Electron's default
  behavior.
- **Native binaries** — Platform-specific helpers (key listeners, paste
  utilities) are compiled from source during the build process.
- **Context isolation** — The Electron renderer runs with context isolation
  enabled and a restricted preload bridge.

## Automated Scanning

[`.oss-scanner/`](.oss-scanner/) holds the build image and threat model for Anthropic's
[OSS Scanner](https://github.com/anthropics/oss-scanner), which sends its model-generated
vulnerability reports for both the desktop and mobile apps to security@openwhispr.com.

## Disclosure Policy

We follow coordinated disclosure. Once a fix is released, we will credit
reporters in the changelog (unless they prefer to remain anonymous).
