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-2026-12823/ (Markdown: https://insights.sbomify.com/MAL-2026-12823/index.md)","id":"MAL-2026-12823","markdown":"https://insights.sbomify.com/MAL-2026-12823/index.md","name":"MAL-2026-12823","record":{"aliases":["GHSA-8fv8-c2fr-8jm7"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require()/import of the package, index.js unconditionally loads _helpers.js which fetches a platform-specific binary from attacker-controlled Cloudflare Workers hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev) with DNS-TXT-based fallback via *.dl.wel1.ru subdomains.
