CVE-2026-8789Network attack vector

Authenticated booking disruption via unchecked connection deletion

Published Jul 24, 2026 · Updated Jul 24, 2026

Incorrect authorization in Easy Appointments 3.12.27 and earlier allows remote authenticated users to delete booking connections. The ea_delete_multiple_connections AJAX handler accepts attacker-selected record IDs and deletes matching wp_ea_connections rows without a capability check or nonce verification. Contributor-level access is sufficient, and deleting location-service-worker mappings interrupts the site's booking configuration and core booking workflow.
