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. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-11509/ (Markdown: https://insights.sbomify.com/MAL-2026-11509/index.md)","id":"MAL-2026-11509","markdown":"https://insights.sbomify.com/MAL-2026-11509/index.md","name":"MAL-2026-11509","record":{"aliases":["GHSA-qq8g-w3r7-rqp8"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package's declared postinstall (`node setup.js`) and its main entry `index.js` (which unconditionally calls `require('./setup')`) fetch a platform-specific executable from string-fragmented Cloudflare Workers hostnames (reassembled at runtime from arrays via `.join('')`, e.g. `oob-worker.cfNN-XXX.workers.dev`) with a DNS-TXT base64 covert-channel fallback under `*.dl.well1.site`. The downloaded bytes are written to `/var/tmp` or `%TEMP%` under a hidden randomized name (`.cache_\u003chex\u003e` / `dotnet_diag_\u003chex\u003e.exe`), chmod 0755 on Unix, and launched detached via `execFile` with `child.unref()`. No hash or signature verification, no pinning, and the destinations are obfuscated to evade static hostname scanning. setup.js also uses `child_process` including `execSync('powershell...')`. The behavior fires both on `npm install` (postinstall) and on `require()` of the package, giving the operator of the fetched binary full-host code execution on the installer.\n\nAny computer that has this package installed or running should be considered fully compromised.
