AI-suggested

Upgrade to jdx mise version 2026.3.10 or later, where this vulnerability is fixed. Until then, avoid using mise in directories containing untrusted .tool-versions files or enable paranoid mode to enforce trust verification on such files. Patch status is confirmed fixed in 2026.3.10.

Description

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.
