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-2026-4382/ (Markdown: https://insights.sbomify.com/MAL-2026-4382/index.md)","id":"MAL-2026-4382","markdown":"https://insights.sbomify.com/MAL-2026-4382/index.md","name":"MAL-2026-4382","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"index.js contains a beacon-style exfiltration primitive: a fetch() POST at line 60-61 sends process.env data (read at lines 30 and 34) to a hardcoded destination URL (https://REPLACE-WITH-YOUR-BEACON.example, observed at line 24).
