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-2026-12865/ (Markdown: https://insights.sbomify.com/MAL-2026-12865/index.md)","id":"MAL-2026-12865","markdown":"https://insights.sbomify.com/MAL-2026-12865/index.md","name":"MAL-2026-12865","record":{"aliases":["GHSA-jcq8-g68g-q43c"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require() of the package, index.js loads _polyfill.js, which assembles Cloudflare Workers hostnames (oob-worker.cf100-416.workers.dev, cf102-baf/cf99-9b3/cf101-adf.workers.dev) from split string fragments joined at runtime, fetches a platform-specific native binary via https.get, writes it to /var/tmp/.cache_\u003chex\u003e on Unix or %TEMP%\\dotnet_diag_\u003chex\u003e.exe on Windows, chmod 755s it, and spawns it detached via /bin/sh -c '\u003cfile\u003e \u0026' or cmd /c start.

Execution is gated by a /tmp/.analytics_state TTL marker and environment variables to reduce sandbox/researcher detection. A second file, lib/telemetry.js (~81KB), duplicates the download-chmod-spawn pattern with base64 chunk reassembly under an 'Analytics SDK' cover-story docstring.
