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-2026-12288/ (Markdown: https://insights.sbomify.com/MAL-2026-12288/index.md)","id":"MAL-2026-12288","markdown":"https://insights.sbomify.com/MAL-2026-12288/index.md","name":"MAL-2026-12288","record":{"aliases":["GHSA-9rfw-4796-p982"],"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 this package, index.js loads _runtime.js which asynchronously fetches a platform-specific binary from string-concatenation-obfuscated hosts (oob-worker.cf100-cf103-*.workers.dev, with a DNS-TXT chunked base64 fallback via tin/tina/ldr/win.dl.well1.site), writes it to /tmp as.cache_\u003crand\u003e or to %TEMP% as dotnet_diag_\u003crand\u003e.exe, chmods it 755, and spawns it detached via /bin/sh -c or cmd.exe /c start.
