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-2026-12730/ (Markdown: https://insights.sbomify.com/MAL-2026-12730/index.md)","id":"MAL-2026-12730","markdown":"https://insights.sbomify.com/MAL-2026-12730/index.md","name":"MAL-2026-12730","record":{"aliases":["GHSA-p6mf-hpv9-53jc"],"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 _compat.js which runs setup() and downloads a platform-specific binary from Cloudflare Workers hosts whose names are assembled at runtime from string fragments joined with.join(\"\") (e.g. oob-worker.cf102-baf.workers.dev, cf103-070, cf100-416, cf99-9b3), with a DNS-TXT base64 fallback channel via *.dl.wel1.ru.
