Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

mise versions before 2026.7.14 are affected. A local, untrusted .mise.toml file in a project directory can set the shell interpreter arguments in its [settings] table, which mise does not strip from untrusted local config, so the attacker's arguments run in place of the default shell arguments. An attacker who gets a user to clone a repository and run mise commands there (such as a task, an install with a postinstall step, or a hook) can execute arbitrary commands without the user trusting the file. Upgrade to mise 2026.7.14 or later.
