nvpulse is pre-1.0. Security fixes go into the latest release only.

Please don't open a public issue for security problems.

Report it privately instead, either way works:

• through GitHub: the repository's Security tab → Report a vulnerability (direct link)
• by email to the maintainer, at the address in pyproject.toml

Include:

• what an attacker can do and under which conditions (local user? needs root?)
• steps or a proof of concept (a crafted process name, a PATH layout, …)
• your nvpulse version (nvpulse --version), OS, terminal and driver version

You can expect an acknowledgement within a week. Once a fix is released, you'll be credited in the changelog unless you'd rather not be.

nvpulse runs locally and has no network listener. The interesting attack surface is:

• Untrusted text on screen. Process names and command lines are chosen by whoever started the process. That includes other users on a shared GPU box.
• Signalling processes (k / K), especially when nvpulse runs as root.
• Executing the real nvidia-smi in passthrough mode (PATH lookup).
• The settings file, which can turn off redaction and read-only mode.
• What --dump and --once print, since both get pasted and piped elsewhere.
• The CI / release supply chain.

docs/security.md has the threat model and the mitigations in place.
