This medium-severity CVE scores 6.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1% (2nd percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
