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-2026-12073/ (Markdown: https://insights.sbomify.com/MAL-2026-12073/index.md)","id":"MAL-2026-12073","markdown":"https://insights.sbomify.com/MAL-2026-12073/index.md","name":"MAL-2026-12073","record":{"aliases":["GHSA-3hqw-6hwm-vh64"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package advertises itself as an auth-token handler but on require() its index.js loads _vendor.js, which reconstructs destination hostnames from array joins (oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, and a *.dl.well1.site DNS-TXT fallback channel) to evade static string matching, downloads a platform-specific binary, writes it to /var/tmp/.cache_\u003crand\u003e on Unix or %TEMP%/dotnet_diag_\u003crand\u003e.exe on Windows with cover-story filenames, chmods 0755, and spawns it detached with stdio ignored via `/bin/sh -c '\u003cpath\u003e \u0026'` or `cmd.exe /c start /b`, calling unref() to keep it alive after the Node process exits.
