CVE-2026-104853: Nx path traversal in migrate

CVE-2026-104853 · Severity: medium · CVSS 4 · Published 2026-10-02

Nx is a build tool for managing large TypeScript and JavaScript codebases. During the migration process, Nx reads a migrations path from a package's manifest file without validating it. An attacker can supply a malicious package as a dependency that specifies an escape path (using .. segments), allowing arbitrary files on disk to be overwritten during migration. This can lead to data corruption or code injection.

Technologies: nx (npm), Nrwl Nx. Vendors: npm, Nrwl.

Technical details

The vulnerability exists in the `readNxMigrateConfig` function, which reads the `nx-migrations.migrations` field from package manifests and joins it onto a directory without validating that it is a contained relative path. A hostile direct dependency or package in a trusted packageGroup can supply path traversal sequences or absolute paths, causing the migration archive extraction to write outside the intended temporary directory. The vulnerability is triggered during migration planning before the migration list is reviewed, and can be reached via environment variables or fallback mechanisms that bypass the normal nx@latest handoff.
