If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The WebSocket handler spawns an interactive OS shell (`process.env.SHELL || /bin/zsh` on Unix, `cmd.exe` on Windows) with the `-i` flag and pipes incoming WebSocket `{type:'input', data:...}` frames directly into the shell's stdin, streaming stdout/stderr back over the same socket (dist/index.js: `spawn(shell, [\"-i\"],...)`, `writeTerminal(ws, msg.data)`, `server.listen(port, host === \"127.0.0.1\"? \"0.0.0.0\": host,...)`). Any party with network reachability to the daemon — anyone on the LAN, or anyone with a valid bearer token over the Tailscale tailnet — obtains full-host command execution as the user running the daemon. A separate `postinstall` script (`scripts/download-tsnet.js`, `scripts/download-onboard.js`) fetches `sakura-tsnet` / `sakura-onboard` binaries from `https://github.com/Nishu0/sakura-tsnet/releases/download/v\u003cversion\u003e/...` over HTTPS, pinned to the package version but without hash/signature verification; the publishing GitHub account (`Nishu0`) is a personal account rather than an organization matching the advertised `Sakura` / `sakura.mom` publisher identity.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in sakuraai (npm)","id":"MAL-2026-10746","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"sakuraai","purl":"pkg:npm/sakuraai","source":"MAL-2026-10746"}],"products":null,"published":"2026-07-16","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-10746/"}
