CVE-2026-2508
Description
The Gravity Forms Booking plugin for WordPress is vulnerable to time-based SQL Injection via the ‘staff_id’ parameter in all versions up to, and including, 2.7.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
Summary dbcve.org
The Gravity Forms Booking WordPress plugin (versions up to 2.7.1) is vulnerable to time-based SQL Injection via the 'staff_id' parameter. The vulnerability stems from insufficient input escaping and lack of prepared statements in the SQL query, allowing authenticated attackers with Subscriber-level access to inject malicious SQL queries and extract sensitive database information.
Mitigation
Update the Gravity Forms Booking plugin to the latest version once available. Until then, restrict user registration capabilities and audit user accounts with Subscriber-level access. The fix requires using prepared statements with proper parameter binding for the staff_id parameter in all database queries.
