FKIE_CVE-2026-54557

Vulnerability from fkie_nvd - Published: 2026-06-26 18:17 - Updated: 2026-06-26 20:20
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N
Summary
mise manages dev tools like node, python, cmake, and terraform. Prior to 2026.6.1, the mise HTTP backend builds its install symlink destination from the raw resolved version string for non-latest versions. Normal tool install paths use the sanitized version pathname, but the HTTP backend's symlink path uses the raw value. On Unix-like systems, if that version is an absolute path, PathBuf::join discards the intended mise installs root. A repository-controlled .tool-versions file can therefore make mise install create a symlink outside the mise install tree. With bin_path, the same issue can place an executable symlink under an attacker-selected absolute prefix, such as a developer-tool prefix that is later added to PATH. This vulnerability is fixed in 2026.6.1.
