CVE-2026-8690Public exploitNetwork attack vector

Unauthenticated rental-data manipulation via unchecked AJAX action

Published Jun 24, 2026 · Updated Jun 24, 2026

Missing authorization in RentMy Real-Time Rental Management Plugin 4.0.4.1 and earlier allows remote attackers to alter rental data. The rentmy_cdn_request AJAX action exposes handlers in class-rentmy-ajax.php that access rentmy_events and update rentmy_locationId without an authorization check. No account is required to read, create, update, or delete stored event records or overwrite the configured location identifier.
