mise manages dev tools like node, python, cmake, and terraform. From 2026.2.18 through 2026.4.5, mise loads trust-control settings from a local project .mise.toml before the trust check runs. An attacker who can place a malicious .mise.toml in a repository can make that same file appear trusted and then reach dangerous directives such as [env] _.source, templates, hooks, or tasks.
