Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
CVE CVE-2026-91024
CVSS 6.5 (Medium)
Publicly Published September 21, 2026
Last Updated September 29, 2026
Researcher Mohamed Bassia

Description

The Booking Manager plugin for WordPress is vulnerable to SQL Injection in all versions up to, and including, 2.1.20. This is 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 author-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
