Event Tickets exposes unauthenticated order-status changes
Event Tickets and Registration before 5.29.0.1 registers an order-management REST endpoint without an authorization check. An unauthenticated visitor can select an existing order and change its status, corrupting ticket-order state without a WordPress account. The published record does not disclose the route, order-ID and status parameters, permission callback, allowed status values or update function.

Update, patch or deactivate.
Update Event Tickets and Registration to 5.29.0.1 or later. Reconcile order statuses with payment and attendance records, review unauthenticated REST activity for sequential order identifiers, and restore altered orders before fulfillment or event admission decisions.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
