CVE-2026-71477: Jdx Mise

Medium severity, CVSS 6.7. EPSS: 0.1% chance of exploitation in the next 30 days.

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

• Jdx Mise: before 2026.7.1 (fixed in 2026.7.1)
