{"cve":"CVE-2026-55441","nvd":{"published":"2026-06-26T18:17:01.190","modified":"2026-10-25T17:10:00.197","status":"Deferred","description":"mise manages dev tools like node, python, cmake, and terraform. Prior to 2026.6.4, mise's trust feature gates config files (mise.toml, .tool-versions) through trust_check, but task-include files are loaded on a path that never reaches it. When a directory has a task-include dir (mise-tasks/, .mise/tasks/, …) but no config file, mise falls back to the default includes and renders each task's tera fields — and that tera environment has exec() registered. A {{ exec(command='…') }} in any rendered field runs arbitrary commands the moment the tasks are merely listed. There's no config file to gate on, so no trust prompt ever appears. Read-only commands trigger it: mise tasks, mise task ls, mise run, mise tasks --usage (the query shell completion runs on Tab). The victim only has to cd into a cloned repo and list or tab-complete a task. This vulnerability is fixed in 2026.6.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":8.6},"cwes":["CWE-78","CWE-94","CWE-732"],"references":["https://github.com/jdx/mise/security/advisories/GHSA-77g9-363w-rccq"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-55441","score":0.00184,"percentile":0.07897,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-77g9-363w-rccq","url":"https://osv.dev/vulnerability/GHSA-77g9-363w-rccq","summary":"Mise vulnerable to arbitrary command execution via task-include files in an untrusted, config-less repository","modified":"2026-06-23T18:41:30.808196Z","packages":[{"ecosystem":"crates.io","name":"mise","purl":"pkg:cargo/mise","ranges":["<2026.6.4"],"fixed":["2026.6.4"]}]}],"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).
