Description

WordPress Booking Calendar Contact Form version 1.0.23 contains an unauthenticated blind SQL injection vulnerability that allows remote attackers to execute arbitrary SQL queries by injecting malicious code through the 'id' parameter. Attackers can send requests to the admin-ajax.php endpoint with the action parameter set to 'dex_bccf_calendar_ajaxevent' and supply crafted SQL commands in the 'id' parameter to extract sensitive database information.
