Directory deletion via reserved manifest bin names
Published Jun 25, 2026 · Updated Jun 25, 2026
Path traversal in pnpm before 10.34.2 and 11.0.0 through 11.5.2 allows remote attackers to delete local directories via a malicious package. Installed manifests can retain empty, dot, or dot-dot bin keys; global remove, update, or replacement joins each key to the global bin path and recursively removes the result. Exploitation requires a user or automation to install the package globally and later perform a global package operation, allowing deletion of the global bin directory or its parent.
