Connections Business Directory <= 10.4.67 - Unauthenticated Non-Public Directory Entry Disclosure via cn-api/v1 REST Routes

Description

The plugin does not apply its visibility and moderation-status restrictions on certain REST API read endpoints, allowing unauthenticated attackers to retrieve directory entries that are marked private or unlisted, or that are still pending moderation, including entry names, organizations, biographies, internal notes and street addresses.
The plugin has been closed on WordPress.org and no fixed version is available, so site owners should remove it or restrict unauthenticated access to its REST API routes.
