#
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.yeoman-environment 6.0.1, which adds an interactive confirmation prompt before installation ([PR #753](https://github.com/yeoman/environment/pull/753)).Sigma rules, YARA signatures, IOC table, and SIEM queries for Splunk, Elastic, Sentinel, and Chronicle — deployable in 5 minutes.
