Unauthenticated booking disclosure via tokenless identifier lookup
Published Aug 10, 2026 · Updated Aug 10, 2026
Information disclosure in Salon Booking System through 10.30.33 allows remote attackers to read other customers' booking records. The confirmation and summary handlers accept sequential booking IDs and load the selected record without checking its per-booking ownership token. No account is required, but a public booking page and an existing booking are necessary; names require a pending booking and multiple services.
