Improper Privilege Management vulnerability in SAASPROJECT Booking Package Booking Package allows Privilege Escalation.This issue affects Booking Package: from n/a through 1.5.98.

Unauthenticated Broken Access Control in Booking Package <= 1.7.06 versions.

The Booking Package WordPress plugin before 1.7.25 does not validate the payment amount server-side against the stored service price, deriving the expected charge from attacker-supplied request values instead, so an unauthenticated attacker can pay an arbitrary fraction of a service's real price.

The Booking Package WordPress plugin before 1.7.31 does not perform any authorization or validity check before resetting its premium subscription state, allowing unauthenticated attackers to disable the Booking Package WordPress plugin before 1.7.31's paid features.

The Booking Package WordPress plugin before 1.7.31 does not perform authorization checks before returning calendar-account configuration in a response, allowing unauthenticated users to disclose sensitive settings including the administrator's notification email addresses.

The Booking Package WordPress plugin before 1.7.33 does not restrict who can trigger its booking verification-code emails nor bind the recipient to server-side state, allowing unauthenticated users to make the site send templated verification-code emails to arbitrary recipients.

The Booking Package WordPress plugin before 1.7.31 does not generate booking cancellation tokens using a secure source of randomness, deriving them instead from values it exposes publicly, so an unauthenticated attacker can reconstruct an arbitrary booking's token, disclose that booking's personal data and, where visitor cancellation is enabled, cancel the booking.
