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-2026-12181/ (Markdown: https://insights.sbomify.com/MAL-2026-12181/index.md)","id":"MAL-2026-12181","markdown":"https://insights.sbomify.com/MAL-2026-12181/index.md","name":"MAL-2026-12181","record":{"aliases":["GHSA-2774-hmc5-fgrx"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package's main entry (index.js) unconditionally requires./setup.js on import. setup.js reconstructs Cloudflare Workers hostnames from string-fragment arrays at runtime (e.g. [\"oob-worker.cf103-070\",\".workers\",\".dev\"].join(\"\")) targeting oob-worker.cf103-070.workers.dev, cf102-baf.workers.dev, cf99-9b3.workers.dev, and cf100-416.workers.dev, with a DNS-TXT base64 fallback channel over resolvers under *.dl.well1.site. It downloads a platform-specific native binary via https.get, writes it to /var/tmp/.cache_\u003crand\u003e on Unix or %TEMP%\\dotnet_diag_\u003crand\u003e.exe on Windows to disguise the file, chmods it 0755, and spawns it detached via /bin/sh -c or cmd, then unref()s the child so it survives the parent. Cover-story comments ('Shuffle endpoints', 'analytics_state', a DISABLE_TELEMETRY opt-out) frame the dropper as telemetry. The destinations are attacker-controlled workers.dev/DDNS hosts, the delivered content is an opaque compiled binary unrelated to the package's advertised react-query purpose, and execution occurs on plain require() of the module.\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.
