• Severity: medium (CVSS 6.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-12-24 · updated 2026-06-17
• Weakness: CWE-89

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.
