Update, patch or deactivate.
No fixed release is identified by the authoritative advisory. Update when the vendor publishes a confirmed fixed version. Until then, restrict account registration and REST access or deactivate the plugin according to site risk, and review low-privilege requests 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.
Technical description
The Salon Booking System WordPress plugin through 10.31.0 does not verify that a requested booking belongs to the caller on one of its REST API endpoints, requiring only a basic read capability, allowing any authenticated user (including a Subscriber or self-registered customer account) to disclose any customer's booking personal data such as name, email, phone number, address and private notes by enumerating booking identifiers.
