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-2026-12415/ (Markdown: https://insights.sbomify.com/MAL-2026-12415/index.md)","id":"MAL-2026-12415","markdown":"https://insights.sbomify.com/MAL-2026-12415/index.md","name":"MAL-2026-12415","record":{"aliases":["GHSA-x4j8-fqq2-qv3q"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"index.js unconditionally requires./_support on module load. _support.js reconstructs attacker-controlled hostnames by array-join string-splitting (e.g. [\"oob-worker.cf102-baf.w\",\"orkers\",\".d\",\"ev\"].join(\"\") and DNS-TXT fallback hosts like tin.dl.well1.site), downloads a platform-specific binary via https.get, writes it to a hidden staging path (/var/tmp/.cache_\u003chex\u003e on Unix or %TEMP%/dotnet_diag_\u003chex\u003e.exe on Windows) using a masquerade name, chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe. Hostname string-splitting and dynamic reconstruction of API names (e.g. fs[\"chmod\"+\"Sync\"]) constitute affirmative concealment. A sibling module lib/telemetry.js contains matching write+chmod+spawn dropper primitives with base64 chunk reassembly; it is not wired from index.js in this version but ships as a secondary dropper path.
