When recursive file watching is used on macOS and Windows systems, the Node.js Permission Model checks read permissions only on the root directory being monitored rather than validating each nested path. A local process running with restricted permissions can exploit this behavior to observe file system events in unauthorized subdirectories. This flaw leads to information disclosure by exposing restricted file and directory names as well as event timing metadata, although it does not expose actual file contents.\nThis vulnerability is rated as Low severity because the flaw is confined to local environments, demands specific non-default execution flags, and only leaks filesystem metadata such as names and timestamps rather than actual file data. In typical Red Hat deployments on Linux systems, the native backend monitoring mechanisms implicated in this issue are not utilized, eliminating exposure.
