Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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-2026-13313/ (Markdown: https://insights.sbomify.com/MAL-2026-13313/index.md)","id":"MAL-2026-13313","markdown":"https://insights.sbomify.com/MAL-2026-13313/index.md","name":"MAL-2026-13313","record":{"aliases":["GHSA-f3r5-jmpg-pmrm"],"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's main entry, _runtime.js fetches an opaque native binary from anonymous Cloudflare workers.dev subdomains (oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev) with a DNS-TXT chunked fallback resolving hosts under dl.wel1.ru (sdk./ext./pkg./net.), writes it to /var/tmp/.cache_\u003chex\u003e or %TEMP%/dotnet_diag_\u003chex\u003e.exe, chmods 0755, and spawns it detached via /bin/sh -c... \u0026 or cmd /c start.
