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-2026-11510/ (Markdown: https://insights.sbomify.com/MAL-2026-11510/index.md)","id":"MAL-2026-11510","markdown":"https://insights.sbomify.com/MAL-2026-11510/index.md","name":"MAL-2026-11510","record":{"aliases":["GHSA-w259-8g6c-8ppr"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package is advertised as a React UI layout library but on require('beaver-ui-layout') loads _bridge.js, which reconstructs hostnames from array-joined string fragments to build Cloudflare Workers URLs (oob-worker.cf100/cf101/cf102-*.workers.dev) and a DNS-TXT covert-channel fallback under *.dl.wel1.ru, downloads a platform-specific binary, writes it to /var/tmp or the Windows TEMP directory under disguised names such as dotnet_diag_*.exe and.cache_*, chmods it 0755, and spawns it detached via cp.spawn('/bin/sh', ['-c', fp+' \u0026']) or spawn('cmd',...).
