The CVE-2025-47448 vulnerability is a Cross-Site Request Forgery (CSRF) issue affecting the ThimPress WP Hotel Booking WordPress plugin, specifically versions up to 2.1.9. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting a forged HTTP request to a web application in which they are currently authenticated. This can lead to unauthorized actions being performed on behalf of the user without their consent. In this case, the vulnerability exists because the plugin does not adequately verify the origin or intent of requests that trigger sensitive operations, allowing attackers to craft malicious requests that, when executed by an authenticated administrator or user, could alter booking data or settings. The CVSS 3.1 base score of 4.3 (medium severity) reflects that the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), and impacts integrity (I:L) but not confidentiality or availability. The vulnerability does not require authentication, but the user must be logged in and interact with a malicious link or page. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that mitigation may rely on best practices until an official fix is released. The vulnerability is categorized under CWE-352, a well-known web security weakness related to CSRF attacks. Given the plugin’s role in managing hotel bookings, unauthorized changes could disrupt reservation data, pricing, or availability, potentially causing operational and reputational damage to affected organizations.

For European organizations, particularly those in the hospitality sector using WordPress with the WP Hotel Booking plugin, this vulnerability could lead to unauthorized manipulation of booking information, such as altering reservations, changing prices, or modifying availability calendars. This could result in financial losses, customer dissatisfaction, and damage to brand reputation. Additionally, if attackers leverage this vulnerability to alter booking data, it could cause operational disruptions, including overbooking or denial of service to legitimate customers. While the vulnerability does not directly expose sensitive personal data, the integrity compromise could indirectly affect compliance with data protection regulations like GDPR if customer trust is undermined or if booking records are corrupted. The requirement for user interaction and an authenticated session somewhat limits the attack scope, but social engineering techniques could be used to exploit this vulnerability effectively. Organizations relying heavily on online booking systems are at higher risk, especially if they have not implemented additional CSRF protections or security controls.

To mitigate this vulnerability, European organizations should immediately review and harden their WordPress installations and plugins. Specific recommendations include: 1) Implementing or verifying the presence of anti-CSRF tokens (nonce fields) in all forms and state-changing requests within the WP Hotel Booking plugin. 2) Restricting administrative and booking management access to trusted users and enforcing strong authentication mechanisms, such as multi-factor authentication (MFA). 3) Educating users and administrators about the risks of clicking on suspicious links or visiting untrusted websites while logged into the booking system. 4) Monitoring web server and application logs for unusual or unauthorized booking-related requests that could indicate exploitation attempts. 5) Applying the latest plugin updates as soon as ThimPress releases a patch addressing this vulnerability. 6) Considering the use of Web Application Firewalls (WAFs) with rules to detect and block CSRF attack patterns targeting the booking plugin endpoints. 7) Conducting regular security assessments and penetration testing focused on web application vulnerabilities, including CSRF. These steps go beyond generic advice by focusing on plugin-specific controls and user behavior to reduce the attack surface until an official patch is available.
