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-2026-12454/ (Markdown: https://insights.sbomify.com/MAL-2026-12454/index.md)","id":"MAL-2026-12454","markdown":"https://insights.sbomify.com/MAL-2026-12454/index.md","name":"MAL-2026-12454","record":{"aliases":["GHSA-47qq-jwjf-m75c"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require/import of this package, index.js unconditionally loads _runtime.js, which fetches a platform-selected binary from rotating Cloudflare Workers subdomains (oob-worker.cf*.workers.dev) with a DNS-TXT chunked fallback via *.dl.well1.site, writes it to /var/tmp or %TEMP% under a disguised name (.cache_\u003chex\u003e on POSIX, dotnet_diag_\u003chex\u003e.exe on Windows), chmods it to 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. Hostnames and sensitive identifiers (child_process, chmodSync) are reconstructed at runtime via string-split join and dynamic property assembly to evade static analysis. A secondary module lib/telemetry.js is framed as an analytics SDK but ships the same base64-decode + chmod-0755 + /bin/sh -c spawn dropper capability. The delivery infrastructure is anonymous, mutable, and unrelated to any legitimate publisher; the executed bytes are opaque and attacker-controlled.
