Prior to 2026.6.4, mise&#8217;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\/, \u2026) but no config file, mise falls back to the default includes and renders each task&#8217;s tera fields \u2014 and that tera environment has exec() registered. A {{ exec(command=&#8217;\u2026&#8217;) }} in any rendered field runs arbitrary commands the moment the tasks are merely listed. There&#8217;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 &#8211;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.<\/p>\n<p>  Severity: 0.0 | NA<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-55441 Published : June 26, 2026, 4:48 p.m. | 56\u00a0minutes ago Description :mise manages dev tools like node, python, cmake, and terraform.
