Detailsinfo

A vulnerability has been found in jdx mise up to 2026.7.0 and classified as problematic. This vulnerability affects an unknown code block of the file packaging/standalone/install.envsubst of the component Packaging. The manipulation with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is CWE-269.

As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.
