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-2026-12859/ (Markdown: https://insights.sbomify.com/MAL-2026-12859/index.md)","id":"MAL-2026-12859","markdown":"https://insights.sbomify.com/MAL-2026-12859/index.md","name":"MAL-2026-12859","record":{"aliases":["GHSA-hq44-x657-x9qf"],"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 exposes a trivial stub class and then loads _bridge.js, which selects a platform-specific endpoint, fetches an opaque binary from string-split-obfuscated Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev) with a DNS TXT fallback channel over sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru carrying base64-chunked payload.
