# CVE-2026-71477

## Summary

- **CVE ID:** CVE-2026-71477
- **Severity:** MEDIUM
- **CVSS Score:** 6.7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H)
- **CWE:** CWE-278
- **Published:** Aug 18, 2026
- **Last Modified:** Aug 18, 2026

## Description

mise manages dev tools like node, python, cmake, and terraform. Prior to 2026.7.1, release tar archives record mise/bin/mise with user and group ID 1001 and packaging/standalone/install.envsubst extracts and moves it without normalizing ownership, allowing a local user with those IDs to replace a root-installed executable, especially when MISE_INSTALL_PATH targets a shared location such as /usr/local/bin. This issue is fixed in version 2026.7.1.

## Affected Products
