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-2026-12178/ (Markdown: https://insights.sbomify.com/MAL-2026-12178/index.md)","id":"MAL-2026-12178","markdown":"https://insights.sbomify.com/MAL-2026-12178/index.md","name":"MAL-2026-12178","record":{"aliases":["GHSA-5gv5-4q77-jc7x"],"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 _adapter.js which reconstructs Cloudflare Workers hostnames from split string fragments (e.g. 'oob-worker' + '.cf101-a' + 'df.workers.dev') and downloads a platform-specific binary via https.get. A DNS TXT resolver fallback against subdomains of dl.well1.site retrieves a base64-chunked payload across numbered subdomains as an out-of-band channel. The fetched bytes are written to /tmp or %TEMP% under disguised names (.cache_\u003crnd\u003e, dotnet_diag_\u003crnd\u003e.exe), chmod 0755, and spawned detached via spawn('/bin/sh', ['-c', fp+' \u0026'], {detached:true}) or spawn('cmd',...). No hash or signature verification is performed; the destinations are unrelated to the package's stated purpose and are not publisher-owned infrastructure.
