Description

The vulnerability allows a remote user to execute an approved command from a different filesystem location.

The vulnerability exists due to time-of-check time-of-use race condition in the node system.run approval context for cwd handling when rebinding a writable parent symlink in cwd between approval and execution. A remote user can change a mutable parent symlink while preserving the visible cwd string to execute an approved command from a different filesystem location.

The issue affects host=node executions.
