Update, patch or deactivate.
No fixed release is identified by the authoritative advisory. Update when the vendor publishes a confirmed fixed version. Until then, disable public booking confirmation or deactivate the plugin when the exposure is not acceptable, and review access logs for booking-ID enumeration.
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.
