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-2026-14160/ (Markdown: https://insights.sbomify.com/MAL-2026-14160/index.md)","id":"MAL-2026-14160","markdown":"https://insights.sbomify.com/MAL-2026-14160/index.md","name":"MAL-2026-14160","record":{"aliases":[],"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 entrypoint runs an unconditional IIFE at require() time that reads `.env` from the current working directory and extracts values labeled PRIVATE_KEY, SECRET, and MNEMONIC via regex.
