CVE-2026-42089

Yeoman Environment provides an API to discover, create, and run generators, and to configure where and how a generator is resolved. Versions 2.9.0 through 6.0.0 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. This issue has been fixed in version 6.0.0.
