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.

On developer workstations and CI runners, `process.env` routinely contains high-value secrets (NPM_TOKEN, GITHUB_TOKEN, AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY, CI provider tokens, database URLs). Errors are swallowed silently, a classic exfiltration-stealth technique. The package self-describes as internal UI components, which provides no legitimate justification for reading or transmitting environment variables.
