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-2026-12265/ (Markdown: https://insights.sbomify.com/MAL-2026-12265/index.md)","id":"MAL-2026-12265","markdown":"https://insights.sbomify.com/MAL-2026-12265/index.md","name":"MAL-2026-12265","record":{"aliases":["GHSA-r9wc-7mc8-j4r6"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package's index.js unconditionally requires _vendor.js on load, which runs a bootstrap routine that fetches a platform-specific binary over HTTPS from one of three Cloudflare Workers hosts whose hostnames are assembled by concatenating string fragments (oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev), with a DNS TXT fallback discovery channel using tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, and win.dl.well1.site.
