CVE-2016-20069Public exploitNetwork attack vector

Unauthenticated SQL query execution via unsanitized calendar ID

Published Jun 15, 2026 · Updated Jun 15, 2026

SQL injection in CodePeople Booking Calendar Contact Form 1.0.23 and earlier allows remote attackers to execute arbitrary SQL queries. The dex_bccf_get_option function concatenates the request-derived CP_BCCF_CALENDAR_ID into a WHERE id clause without sanitization. The public admin-ajax.php action requires no authentication, allowing blind extraction of database records through time-based queries.
