      "value": "mise manages dev tools like node, python, cmake, and terraform. Prior to 2026.3.10, mise processes .tool-versions files through the Tera template engine during parsing, with the exec() function registered, enabling arbitrary command execution. Unlike .mise.toml files, .tool-versions files are not subject to trust verification in non-paranoid mode. This means an attacker can place a malicious .tool-versions file in a git repository, and when a victim with mise activated cds into the directory, arbitrary commands execute without any trust prompt. This vulnerability is fixed in 2026.3.10."

      "value": "mise gestiona herramientas de desarrollo como node, python, cmake y terraform. Antes de la versión 2026.3.10, mise procesa los archivos .tool-versions a través del motor de plantillas Tera durante el análisis, con la función exec() registrada, lo que permite la ejecución arbitraria de comandos. A diferencia de los archivos .mise.toml, los archivos .tool-versions no están sujetos a verificación de confianza en modo no paranoico. Esto significa que un atacante puede colocar un archivo .tool-versions malicioso en un repositorio git, y cuando una víctima con mise activado cambia al directorio, se ejecutan comandos arbitrarios sin ninguna solicitud de confianza. Esta vulnerabilidad está corregida en la versión 2026.3.10."
