unity-cli is a command line utility for the Unity Game Engine. Prior to 1.8.2 , the sign-package command in @rage-against-the-pixel/unity-cli logs sensitive credentials in plaintext when the --verbose flag is used. Command-line arguments including --email and --password are output via JSON.stringify without sanitization, exposing secrets to shell history, CI/CD logs, and log aggregation systems. This vulnerability is fixed in 1.8.2.
