CVE-2026-15238 in Hotel Booking Plugin
Summary
by MITRE • 08/10/2026
The MotoPress Hotel Booking WordPress plugin before 6.2.3 does not verify record ownership before updating customer records, allowing any authenticated user with a low-privileged account (Subscriber and above) to modify or overwrite the personal data of any customer by supplying an arbitrary identifier.

The vulnerability in the MotoPress Hotel Booking WordPress plugin affects versions prior to 6.2.3 and represents a critical access control flaw that undermines the integrity of customer data management within hotel reservation systems. This issue stems from insufficient record ownership verification mechanisms during update operations, creating a scenario where unauthorized modifications can occur through simple parameter manipulation. The flaw specifically targets authenticated users who possess subscriber-level privileges or higher, which is particularly concerning given that many WordPress installations have numerous low-privileged accounts for various operational functions including customer support, content management, and administrative tasks.
The technical implementation of this vulnerability resides in the plugin's data handling routines where customer record updates do not validate whether the requesting user has legitimate authorization to modify the specified record. This design flaw allows an attacker with minimal privileges to construct malicious requests that target specific customer identifiers, effectively bypassing normal access controls and enabling arbitrary data modification. The vulnerability operates at the application level and can be exploited through direct API calls or by manipulating form parameters within the plugin's administrative interface, making it particularly dangerous as it does not require advanced technical skills or elevated privileges beyond basic user authentication.
The operational impact of this vulnerability extends far beyond simple data corruption, potentially enabling significant harm to both businesses and end users. An attacker could modify customer personal information including names, contact details, booking references, or payment information, leading to potential fraud, service disruption, and loss of customer trust. The implications are particularly severe for hospitality businesses that rely on accurate customer data for check-in processes, communication, and compliance with data protection regulations such as gdpr and ccpa. Additionally, the ability to overwrite critical booking information could result in double bookings, cancellation issues, or revenue loss for hotel operators who depend on accurate reservation management.
This vulnerability aligns with CWE-639 Access Control Flaw category which specifically addresses situations where applications fail to properly verify user authorization for data access and modification operations. The issue also maps to ATT&CK technique T1078 Valid Accounts, as it exploits legitimate user accounts with existing privileges rather than requiring account compromise through other attack vectors. Organizations should implement immediate mitigations including updating to version 6.2.3 or later, implementing additional access control layers such as role-based permissions that limit customer data modification capabilities to specific administrative roles only, and conducting thorough audits of all plugin configurations. Network monitoring should be enhanced to detect suspicious update patterns, while regular security assessments of WordPress plugins should be conducted to identify similar access control weaknesses in other third-party components. The vulnerability underscores the critical importance of proper input validation and authorization checking in web applications, particularly those handling sensitive customer data within e-commerce and hospitality environments.
