# CVE-2024-10856: Booking Calendar WpDevArt \<= 3.2.19 - Authenticated (Contributor+) SQL Injection

- Severity: CVSS 6.5 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

- Published: 2024-12-24 · Updated: 2026-04-08

## Affected

- wpdevart Booking calendar, Appointment Booking System: through 3.2.19

## Description

The Booking Calendar WpDevArt plugin is vulnerable to time-based, blind SQL injection via the `id` parameter in the “wpdevart_booking_calendar” shortcode in versions up to, and including, 3.2.19 due to insufficient escaping on the user-supplied parameter and lack of sufficient preparation on the existing SQL query. The vulnerability requires the “delete_prev_date” theme option being enabled. This makes it possible for authenticated attackers, with contributor-level access or above, to append additional SQL queries into already existing query that can be used to extract sensitive information such as passwords from the database.
