CVE-2026-35533: mise manages dev tools like node, python, cmake, and terraform

Routine

HIGH 7.7UPGRADE

CVE-2026-35533 is a high-severity flaw (CVSS 7.7) affecting mise. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

mise manages dev tools like node, python, cmake, and terraform. From 2026.2.18 through 2026.4.5, mise loads trust-control settings from a local project .mise.toml before the trust check runs. An attacker who can place a malicious .mise.toml in a repository can make that same file appear trusted and then reach dangerous directives such as [env] _.source, templates, hooks, or tasks.

jdx mise UPGRADE

Affected: >= 2026.2.18 and <= 2026.4.5

Fixed in: newer than 2026.4.5

Safe to downgrade to: a release before 2026.2.18

1. Check installed version

apt-cache policy mise || rpm -q mise || mise --version

2. UPGRADE to newer than 2026.4.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade mise

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade mise

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2026.2.18 (Debian / Ubuntu)

apt-cache madison mise sudo apt install mise=<VERSION_BEFORE_2026.2.18> sudo apt-mark hold mise

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list mise sudo dnf downgrade mise-<VERSION_BEFORE_2026.2.18> sudo dnf versionlock add mise

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
