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.","state":0,"publishedAt":"2026-06-26T16:48:23.194+00:00","modifiedAt":"2026-06-26T18:41:26.486+00:00","affected":[{"ecosystem":"Vendor product","name":"mise","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"jdx\",\n                    \"product\": \"mise\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2026.6.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://github.com/jdx/mise/security/advisories/GHSA-77g9-363w-rccq"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55441","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55441","identifiers":["CVE-2026-55441"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
