# Booking Package WordPress plugin leaks calendar settings and admin email addresses

The Booking Package WordPress plugin before 1.7.31 returns calendar-account configuration without checking who is asking. An unauthenticated visitor can read those settings, including the site administrator's notification email addresses.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed version of the Booking Package plugin in the WordPress admin plugin list or `wp plugin get booking-package --field=version` (the plugin slug is unknown from the sources; confirm it).
- Confirm whether the plugin is active on the site.

## Fix

- Update the Booking Package plugin to `1.7.31` or later.

## From the sources

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.
