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-2026-12301/ (Markdown: https://insights.sbomify.com/MAL-2026-12301/index.md)","id":"MAL-2026-12301","markdown":"https://insights.sbomify.com/MAL-2026-12301/index.md","name":"MAL-2026-12301","record":{"aliases":["GHSA-xp7w-qh77-w69x"],"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./_init on module load. _init.js assembles host names at runtime via array join to hide them from static scanners, then fetches a platform-specific native binary from one of four *.workers.dev hosts (oob-worker.cf101-adf.workers.dev, cf99-9b3.workers.dev, cf103-070.workers.dev, cf100-416.workers.dev), with a DNS TXT base64 fallback channel enumerated over c.\u003cresolver\u003e and 0..N.\u003cresolver\u003e records under tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, and win.dl.well1.site.
