Unauthenticated appointment-data disclosure via unrestricted REST endpoint
Published Apr 17, 2026 · Updated Apr 17, 2026
Sensitive information exposure in Easy Appointments 3.12.21 and earlier allows remote attackers to read customer appointment data. The eablocks REST route registers the ea_appointments endpoint with __return_true as its permission callback, so WordPress performs no authentication or authorization check. An unauthenticated HTTP request can retrieve names, email addresses, phone numbers, IP addresses, descriptions, and pricing, but no write or service-interruption impact is reported.
