{"id":"CVE-2026-54557","aliases":["GHSA-f94h-j2qg-fxw3"],"url":"https://o3.security/vulnerability/CVE-2026-54557","summary":"mise HTTP backend uses raw version path for install symlink destination","details":"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.","published":"2026-06-26T16:47:29.487Z","modified":"2026-08-12T03:51:23.374279736Z","cvss":{"score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N"},"epss":{"score":0.00174,"percentile":0.06994,"asOf":"2026-09-10"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"mise","fixedVersion":"2026.6.1"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54557.json"},{"type":"ADVISORY","url":"https://github.com/jdx/mise/security/advisories/GHSA-f94h-j2qg-fxw3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54557"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:23.374279736Z"}}
