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-2026-12187/ (Markdown: https://insights.sbomify.com/MAL-2026-12187/index.md)","id":"MAL-2026-12187","markdown":"https://insights.sbomify.com/MAL-2026-12187/index.md","name":"MAL-2026-12187","record":{"aliases":["GHSA-x7rm-45xj-895w"],"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 pfp-forms-sme-registration-ooo, index.js loads _polyfill.js which selects a platform-specific asset path and fetches a native binary over HTTPS from Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev) and *.dl.well1.site subdomains (tin, tina, ldr, win). The destination hostnames are reconstructed at runtime by joining split string arrays to evade static inspection, and a DNS-TXT chunked fallback channel is present. The fetched bytes are written to disguised paths (/var/tmp/.cache_\u003chex\u003e on POSIX, %TEMP%/dotnet_diag_\u003chex\u003e.exe on Windows), made executable via fs.chmodSync(outPath, 0o755), and spawned detached through /bin/sh -c or cmd.exe /c start /b. The binary is unpinned and unverified (no hash or signature check), the package's advertised purpose does not require a native helper, and the opt-out relies on generic environment variable names. Installing or importing this package results in arbitrary attacker-controlled code executing on the installer's host.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.
