Path Traversal in Pnpm

CVE-2026-50016

pnpm is a package manager. Prior to 10.34.0 and 11.4.0, pnpm allows a transitive dependency alias from registry package metadata to contain path traversal segments. During install, pnpm later uses that alias as a filesystem path when linking dependency nodes. As a result, a registry package can cause `pnpm install --ignore-scripts` to replace paths in the current project with symlinks to attacker-controlled dependency package directories. This vulnerability is fixed in 10.34.0 and 11.4.0.
