What to do

Remove @depup/nuxt from every project, lockfile and image that pulls it in. Treat any host that installed it as compromised: rotate the credentials, tokens and keys it could read, from a clean machine.

Description

The @depup/nuxt package version 4.5.0-depup.0 on npm contains malicious code that injects an undocumented dependency '@dxup/nuxt', a lookalike package controlled by attackers. This dependency is automatically loaded as a privileged Nuxt module during build or development when the experimental.typescriptPlugin option is enabled, allowing execution of arbitrary code in the build/dev environment. This behavior is hidden from the package's README and change logs, representing a supply chain compromise via dependency-graph smuggling.

Impact

If a developer installs and uses @depup/nuxt version 4.5.0-depup.0 with experimental.typescriptPlugin enabled, the malicious '@dxup/nuxt' module is auto-loaded with elevated privileges during build or development. This allows attackers to execute arbitrary code in the build environment, potentially compromising the developer's system and any downstream software built with this package. The supply chain compromise undermines trust in the npm ecosystem and can lead to widespread impact if the package is widely used.

Defensive guidance

Users should avoid using the @depup/nuxt package version 4.5.0-depup.0. Verify package authenticity before installation and consider using official Nuxt releases from trusted sources. Monitor vendor advisories and npm security announcements for updates or patches addressing this malicious package. Remove any installations of this package and audit build environments for signs of compromise.

Summary

The @depup/nuxt npm package version 4.5.0-depup.0 masquerades as a routine Nuxt republish with dependency updates but includes two coordinated malicious modifications. First, it injects a runtime dependency on '@dxup/nuxt', which is not documented and does not exist in the legitimate Nuxt 4.5.0 package. Second, the package's distribution code modifies the Nuxt build process to automatically load '@dxup/nuxt' as a privileged module when experimental.typescriptPlugin is enabled, enabling arbitrary code execution in the build or development context. This attack leverages dependency-graph smuggling under the guise of a familiar Nuxt package.
