CVE-2026-24607 identifies a Missing Authorization vulnerability in the wptravelengine Travel Monster WordPress plugin, affecting versions up to and including 1.3.3. The vulnerability stems from incorrectly configured access control security levels, which means that certain functions or data within the plugin can be accessed or manipulated without proper authorization checks. This type of flaw typically allows attackers to bypass intended permission restrictions, potentially enabling unauthorized users to perform privileged actions or access sensitive information. The plugin is designed for travel-related websites, managing bookings, travel packages, or related content, making it a valuable target for attackers seeking to disrupt services or steal customer data. Although no known exploits are currently reported in the wild, the vulnerability's presence in a widely used plugin increases the risk of future exploitation. The lack of a CVSS score indicates that the vulnerability is newly disclosed, and detailed impact metrics are not yet established. However, missing authorization issues generally pose a high risk due to their potential to compromise confidentiality and integrity without requiring user interaction or authentication. The vulnerability's impact could include unauthorized data disclosure, modification of travel bookings or packages, and potential disruption of service. The plugin's user base, particularly in Europe where travel and tourism are significant economic sectors, could face operational and reputational damage if exploited. The absence of patches at the time of disclosure necessitates immediate mitigation steps such as restricting plugin usage, auditing access controls, and monitoring for anomalous activity. Organizations should prepare to apply vendor patches promptly once available and consider compensating controls to limit exposure.

For European organizations, especially those in the travel and tourism industry, this vulnerability could lead to unauthorized access to sensitive customer data, travel itineraries, and booking information, compromising confidentiality and potentially leading to data breaches. Integrity could be affected if attackers modify travel packages or booking details, causing operational disruptions and customer dissatisfaction. Availability impact is less direct but could occur if attackers leverage the vulnerability to disrupt services or cause plugin malfunctions. The risk is heightened in Europe due to the high adoption of WordPress-based travel websites and the economic importance of tourism. Data protection regulations such as GDPR increase the stakes, as breaches involving personal data can result in significant fines and reputational damage. Organizations relying on Travel Monster without proper access control configurations may face increased risk of targeted attacks or opportunistic exploitation. The lack of known exploits currently provides a window for proactive mitigation, but the potential impact remains significant given the nature of the vulnerability.

1. Immediately audit all access control configurations related to the Travel Monster plugin to ensure that only authorized roles have access to sensitive functions and data. 2. Disable or restrict the use of the Travel Monster plugin on production systems until a security patch is released by the vendor. 3. Monitor web server and application logs for unusual access patterns or unauthorized attempts to access restricted plugin functions. 4. Implement strict role-based access control (RBAC) within WordPress, minimizing privileges granted to users and service accounts interacting with the plugin. 5. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin endpoints. 6. Stay informed on vendor communications and apply security patches immediately once they become available. 7. Conduct penetration testing focused on access control mechanisms within the plugin to identify any residual weaknesses. 8. Educate site administrators and developers about secure plugin configuration and the risks of missing authorization vulnerabilities. 9. Consider isolating the plugin functionality or migrating to alternative solutions with stronger security postures if patches are delayed.
