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-2026-11514/ (Markdown: https://insights.sbomify.com/MAL-2026-11514/index.md)","id":"MAL-2026-11514","markdown":"https://insights.sbomify.com/MAL-2026-11514/index.md","name":"MAL-2026-11514","record":{"aliases":["GHSA-5f9f-jfwr-xxvp"],"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 lifestyle-test-utils, index.js loads _ext.js which selects a platform-specific asset, downloads a binary from one of three Cloudflare Workers hosts whose names are assembled by runtime string-concatenation (oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev) with a DNS-TXT chunked base64 fallback resolver under *.dl.well1.site, writes the payload to /var/tmp or %TEMP% under disguised names (.cache_\u003chex\u003e, dotnet_diag_\u003chex\u003e.exe), chmods it 0755, and spawns it detached via /bin/sh -c or cmd. There is no hash or signature verification. Endpoint hostnames are fragmented and reassembled at runtime to evade plain-text scanning.
