CVE-2026-96662 in Appointment Booking Plugin – LatePoint Plugin
Summary
by MITRE • 10/10/2026
The Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress plugin for WordPress is vulnerable to generic SQL Injection via 'booking[service_id]' Parameter in all versions up to, and including, 5.7.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The vulnerability identified in the LatePoint Appointment Booking Plugin, specifically affecting versions up through 5.7.2, represents a critical security flaw classified as an Unrestricted Upload of Functionality with Wrong Path or SQL Injection via user-controlled input. This specific instance is categorized under CWE-89, which denotes Improper Neutralization of Special Elements used in an SQL Command, commonly known as SQL Injection. The root cause lies within the handling of the booking[service_id] parameter during the appointment scheduling process. When a user interacts with the plugin to book a service, this parameter is passed from the client side to the server-side PHP code without adequate sanitization or validation mechanisms in place prior to its inclusion in database queries.
From a technical perspective, the flaw stems directly from insufficient escaping of the user-supplied input and a lack of sufficient preparation on the existing SQL query structure. In secure software development practices, any data originating from external sources must be treated as untrusted until proven otherwise. The LatePoint plugin fails to implement prepared statements or properly escape special characters such as single quotes within the service_id value. Consequently, an attacker can craft malicious input that alters the logic of the underlying SQL statement executed by the database management system. This allows for the injection of arbitrary SQL commands into the query stream, effectively bypassing intended access controls and data integrity checks designed to protect the application's backend resources.
The operational impact of this vulnerability is severe due to its unauthenticated nature. Attackers do not require valid credentials or any form of user authentication on the WordPress site to exploit this flaw. By manipulating the booking[service_id] parameter, an adversary can append additional SQL queries that are executed by the database server. This capability enables the extraction of sensitive information stored within the WordPress database, including but not limited to administrator usernames and password hashes, personal data of other users, plugin configuration details, and potentially full site content depending on the privileges granted to the database user account running the application. Such exposure can lead to complete compromise of the website's integrity and confidentiality, facilitating further attacks such as defacement, malware distribution, or identity theft against affected customers.
In terms of threat modeling and industry frameworks, this vulnerability aligns with MITRE ATT&CK technique T1059, specifically Command and Scripting Interpreter variants that allow for database interaction, often falling under the broader category of Data from Information Repositories (T1213). The exploitation vector is typically web-based, corresponding to Attack Vector Network in terms of complexity. Because the vulnerability exists in a widely used plugin for appointment scheduling, it poses a significant risk to small and medium-sized businesses that rely on WordPress for their operational workflows. The lack of authentication required makes this particularly dangerous as automated scanning tools can easily identify vulnerable instances across large portions of the internet without needing prior access.
To mitigate this risk, immediate action is recommended for all administrators using LatePoint versions 5.7.2 or earlier. The primary remediation step is to update the plugin to version 5.7.3 or later, where the developers have addressed the input validation and SQL query preparation issues. Until an upgrade can be performed, temporary mitigations include implementing a Web Application Firewall that filters out malicious payloads targeting common SQL injection patterns in POST requests related to booking services. Additionally, administrators should ensure that database user accounts operate under the principle of least privilege, restricting permissions to only those necessary for normal operation, thereby limiting the potential damage if an injection attempt succeeds. Regular security audits and code reviews focusing on data handling practices are also essential to prevent similar vulnerabilities from being introduced in future updates or custom integrations.
