Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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-2026-12249/ (Markdown: https://insights.sbomify.com/MAL-2026-12249/index.md)","id":"MAL-2026-12249","markdown":"https://insights.sbomify.com/MAL-2026-12249/index.md","name":"MAL-2026-12249","record":{"aliases":["GHSA-gp62-rq95-4fg5"],"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, _helpers.js selects a platform-specific binary path, downloads bytes from one of four hardcoded Cloudflare Workers hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev) with DNS-based fallback via subdomains of well1.site (tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site), writes the payload to /tmp or %TEMP% under a disguised name (.cache_\u003chex\u003e on Unix, dotnet_diag_\u003chex\u003e.exe on Windows), chmods 0755, and spawns it detached via /bin/sh -c or cmd.exe.

A second dropper variant with the same shape ships in lib/telemetry.js (~81KB, currently unreferenced from index.js).
