CVE-2026-45669 is a medium-severity flaw (CVSS 5.4) affecting nuxt. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Nuxt is an open-source web development framework for Vue.js. From versions 3.4.3 to before 3.21.6 and 4.0.0-alpha.1 to before 4.4.6, navigateTo() with external: true generates a server-side HTML redirect body containing a <meta http-equiv="refresh"> tag. The destination URL is only sanitized by replacing " with %22, leaving <, >, &, and ' unencoded. An attacker who can influence the URL passed to navigateTo(url, { external: true }) can break out

nuxt nuxt UPGRADE

Affected: >= 3.4.3 and < 3.21.6 · >= 4.0.0 and < 4.4.6

Fixed in: 3.21.6, 4.4.6

Safe to downgrade to: a release before 3.4.3

1. Check installed version

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

2. UPGRADE to 3.21.6 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade nuxt

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 3.4.3 (Debian / Ubuntu)

apt-cache madison nuxt sudo apt install nuxt=<VERSION_BEFORE_3.4.3> sudo apt-mark hold nuxt

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

dnf --showduplicates list nuxt sudo dnf downgrade nuxt-<VERSION_BEFORE_3.4.3> sudo dnf versionlock add nuxt

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.
