Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix High confidence

2026.7.1

  1. Check current mise version by running: mise --version
  2. Upgrade mise to version 2026.7.1 or later. If using a package manager, update via: brew update && brew upgrade mise (macOS), or apt-get update && apt-get install mise (Debian/Ubuntu), or your system's package manager
  3. Alternatively, reinstall from the official release: curlfs https:// mise.jdx.dev/install.sh | sh (verify URL from official mise documentation)
  4. Verify the upgrade was successful by running: mise --version
  5. Ensure the installed binary ownership is correct (should be root:root for /usr/local/bin installations)
  6. If previously installed with MISE_INSTALL_PATH=/usr/local/bin, re-run installation as root to ensure proper ownership
