## Affected

- wpdevelop Booking Calendar: through 10.14.13

## Description

The Booking Calendar plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the wpbc_ajax_WPBC_FLEXTIMELINE_NAV() function in all versions up to, and including, 10.14.13. This makes it possible for unauthenticated attackers to retrieve booking information including customer names, phones and emails.

## What to do

- Check your stack: if you ship or depend on wpdevelop Booking Calendar, no fixed version is listed yet; follow the vendor advisory per the references below.
