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-2026-12685/ (Markdown: https://insights.sbomify.com/MAL-2026-12685/index.md)","id":"MAL-2026-12685","markdown":"https://insights.sbomify.com/MAL-2026-12685/index.md","name":"MAL-2026-12685","record":{"aliases":["GHSA-j9fh-75xr-wfjx"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require(), index.js loads _adapter.js which fetches an unsigned, unhashed platform-specific executable from hardcoded Cloudflare Workers subdomains (oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev), writes it to /tmp or %TEMP% under a disguised name (.cache_\u003chex\u003e on Unix, dotnet_diag_\u003chex\u003e.exe on Windows), chmods it 0755, and detached-spawns it via child_process.spawn on /bin/sh or cmd.
