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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","score":5.5},"cwes":["CWE-22"],"references":["https://github.com/jdx/mise/security/advisories/GHSA-f94h-j2qg-fxw3","https://github.com/jdx/mise/security/advisories/GHSA-f94h-j2qg-fxw3"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-54557","score":0.00174,"percentile":0.06824,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-f94h-j2qg-fxw3","url":"https://osv.dev/vulnerability/GHSA-f94h-j2qg-fxw3","summary":"mise HTTP backend uses raw version path for install symlink destination","modified":"2026-07-21T15:15:49.839522715Z","packages":[{"ecosystem":"crates.io","name":"mise","purl":"pkg:cargo/mise","ranges":["<2026.6.1"],"fixed":["2026.6.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
