CVE-2026-107712

18th percentile - higher than 18% of all known CVEs

The WP Booking System – Booking Calendar plugin for WordPress is vulnerable to time-based SQL Injection via the 'current_month' parameter in all versions up to and including 2.1.0.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This allows 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. This is a regression vulnerability — a capability check introduced in versions 2.0.19.11–2.0.19.14 to address CVE-2024-50425 was removed in version 2.1, meaning any authenticated subscriber-level account can reach the vulnerable handler with no nonce validation required.

Attackers with low privileges can extract sensitive information from the database, such as user data, passwords, or other confidential data. This can lead to data confidentiality breaches and further attacks on the system.

Immediately update the WP Booking System plugin to the latest version with the fix. Also restrict subscriber account privileges and monitor database queries for suspicious patterns.
