mise: Arbitrary Code Execution via Tera Templates in .tool-versions Files (Trust Bypass)_CVE-2026-33646

{
    "lastseen": "",
    "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.",
