Only the current stable minor line receives security fixes:

Upgrade to the latest release for security and reliability fixes. See docs/UPDATE.md.

Do not open a public GitHub issue for security vulnerabilities.

Preferred: email the maintainer at jatinkrmalik@gmail.com with subject:

Vocalinux Security Vulnerability Report

Include:

• Clear description of the issue
• Steps to reproduce
• Potential impact
• Suggested fix (optional)

You should receive acknowledgment within 48 hours. We will assess severity, share an expected timeline, coordinate disclosure, and credit you in release notes if you want credit.

If email is unavailable, use GitHub private vulnerability reporting when enabled for the repository.

Vocalinux is built for local-first dictation:

• Local engines process audio on-device after you download a model
• No Voca account is required for local engines
• No usage telemetry in the installed application
• Models download once and stay in local cache
• Downloads are checked against pinned checksums before install

When the user enables Remote API, audio is uploaded to the configured server over HTTP(S). That path is off by default. Operators should use TLS and authentication for any network outside a trusted LAN. See docs/HTTP_REMOTE.md.

1. Text injection uses tools such as xdotool, wtype, ydotool, or IBus; desktop input APIs have their own privilege model
2. Global shortcuts need access to input devices (e.g. evdev on some setups)
3. Virtual environments isolate Python packages but do not sandbox the desktop session

# Re-run the official installer (preserves config and models)
curl -fsSL https://raw.githubusercontent.com/VocaHQ/vocalinux/main/install.sh -o /tmp/vl.sh
bash /tmp/vl.sh
