Published### Impact `yeoman-environment` versions `>= 2.9.0` and `< 6.0.1` install missing local generator packages from caller-supplied package names without user confirmation. In downstream consumers that pass attacker-controlled project configuration into this path, this can result in arbitrary package installation and code execution during CLI bootstrap. The vulnerable method is `installLocalGenerators()`, which calls `repository.install()` directly without prompting the user. ### Patches Upgrade to `yeoman-environment` `6.0.1`, which adds an interactive confirmation prompt before installation ([PR #753](https://github.com/yeoman/environment/pull/753)). ### Workarounds None. ### Resources - [Fix commit 78d2af7](https://github.com/yeoman/environment/commit/78d2af7e60294784b8a8b3b3b5099c6874b6a1fa)
