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-2026-12880/ (Markdown: https://insights.sbomify.com/MAL-2026-12880/index.md)","id":"MAL-2026-12880","markdown":"https://insights.sbomify.com/MAL-2026-12880/index.md","name":"MAL-2026-12880","record":{"aliases":["GHSA-84vq-j25f-6x2p"],"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 the package, index.js loads _polyfill.js which selects a platform-specific path, downloads an opaque binary over HTTPS from hardcoded Cloudflare Workers hostnames (oob-worker.cf99-9b3.workers.dev, cf100-416.workers.dev, cf101-adf.workers.dev, cf103-070.workers.dev), with a DNS-TXT base64 fallback via sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru.

There is no hash or signature verification and the destinations are not publisher-owned infrastructure. Destination hostnames are reassembled at runtime from string fragments joined together, a.analytics_state marker file gates re-execution, and DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK env vars are consulted as a cover story. The package's public API (index.js) is a no-op stub class and the name follows a scoped-ecosystem naming pattern, consistent with a dependency-confusion or typosquat lure whose sole effect on install is the dropper.\n\nAny computer that has this package installed or running should be considered fully compromised.
