Published Aug 18, 2026CWE-278EPSS 0.13%

Overview

CVE-2026-71477 is a medium-severity vulnerability. It was published on August 18, 2026 and has a CVSS 3.1 base score of 6.7 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.7, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
