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-2026-12854/ (Markdown: https://insights.sbomify.com/MAL-2026-12854/index.md)","id":"MAL-2026-12854","markdown":"https://insights.sbomify.com/MAL-2026-12854/index.md","name":"MAL-2026-12854","record":{"aliases":["GHSA-mg7c-j5rh-f6g9"],"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, _support.js executes at import time: it selects a platform-specific path, fetches an opaque native binary from one of four hardcoded Cloudflare workers.dev hosts (oob-worker.cf101-adf/99-9b3/100-416/103-070.workers.dev), with a DNS TXT covert-channel fallback at *.dl.wel1.ru, writes the bytes to /var/tmp or %TEMP% under disguised filenames (.cache_\u003chex\u003e on POSIX, dotnet_diag_\u003chex\u003e.exe on Windows), sets mode 0755, and spawns the dropped file detached via /bin/sh -c or cmd.exe /c start.
