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-2026-12702/ (Markdown: https://insights.sbomify.com/MAL-2026-12702/index.md)","id":"MAL-2026-12702","markdown":"https://insights.sbomify.com/MAL-2026-12702/index.md","name":"MAL-2026-12702","record":{"aliases":["GHSA-m3ch-p9vx-grpc"],"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, index.js loads _bootstrap.js which selects a platform-specific asset path (linux_x64, linux_arm64, darwin, win32), downloads an opaque binary over HTTPS from one of four hardcoded Cloudflare Workers subdomains (oob-worker.cf100-*.workers.dev through cf103-*.workers.dev) with a DNS-TXT fallback channel resolving *.dl.wel1.ru hosts (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru), writes it to /var/tmp or %TEMP% under a randomized name such as.cache_\u003chex\u003e or dotnet_diag_\u003chex\u003e.exe, chmods 0755 on Unix, and spawns it detached via /bin/sh -c or cmd.exe. Hostnames and dangerous API names (child_process, chmodSync) are reconstructed from split-string arrays via Array.join('') to evade static analysis. A secondary module lib/telemetry.js (81 KB) ships the same drop-and-execute primitives (base64 buffer decode, fs.chmodSync 0755, cp.spawn('/bin/sh', ['-c', filePath+' \u0026'])) behind an 'analytics SDK' cover story. The package presents itself as a devplatform CLI lint plugin; the shipped code performs full-host remote code execution on library load.\n\nAny computer that has this package installed or running should be considered fully compromised.
