Quak handles Wi-Fi passwords and stream keys, can change a computer's network, and can delete clips from a camera. If you find a way it could leak those or do something you didn't ask for, please report it privately rather than opening a public issue: use Report a vulnerability on the repository's Security tab.
This is a small project, so replies may take a few days. Fixes go into the latest release.
docs/safety.md describes what Quak is meant to do.
