The Booking Package WordPress plugin before 1.5.29 requires a token for exporting the ical representation of it's booking calendar, but this token is returned in the json response to unauthenticated users performing a booking, leading to a sensitive data disclosure vulnerability.
Cross-site scripting vulnerability in Booking Package - Appointment Booking Calendar System versions prior to 1.5.11 allows a remote attacker to inject an arbitrary script via unspecified vectors.
