CVE-2025-63012 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the ThimPress WP Hotel Booking plugin for WordPress, affecting all versions up to and including 2.2.7. CSRF vulnerabilities enable attackers to induce authenticated users to perform unwanted actions on a web application where they are logged in, by tricking them into submitting malicious requests. In this case, the vulnerability allows an attacker to craft a malicious web page or link that, when visited by an authenticated user of the WP Hotel Booking plugin, could execute unintended actions such as modifying booking details or settings without the user's consent. The CVSS 3.1 base score of 4.3 reflects that the attack vector is network-based (remote), requires no privileges, but does require user interaction (the victim must visit a malicious site). The impact is limited to confidentiality, with no direct effect on integrity or availability, meaning sensitive information could be exposed but data modification or service disruption is not directly possible through this flaw. No known exploits have been reported in the wild, and no patches were linked at the time of publication, indicating that mitigation may require vendor updates or manual security controls. The vulnerability is particularly relevant for organizations relying on the WP Hotel Booking plugin to manage reservations and customer data, as unauthorized actions could lead to data leakage or unauthorized information disclosure. The vulnerability was reserved on 2025-10-24 and published on 2025-12-09, showing a recent disclosure timeline.

For European organizations, especially those in the hospitality and tourism sectors using the WP Hotel Booking plugin, this vulnerability could lead to unauthorized disclosure of booking or customer information, potentially violating data protection regulations such as GDPR. Although the vulnerability does not allow direct data modification or service disruption, the exposure of confidential information could damage customer trust and lead to regulatory penalties. Attackers could exploit this vulnerability to gather sensitive booking details or customer data by tricking authenticated users into executing malicious requests. This risk is heightened in environments where multiple users have elevated privileges or where the plugin is integrated with other critical systems. The medium severity rating suggests that while the threat is not critical, it should not be ignored, especially given the importance of protecting personal data in Europe. Additionally, the lack of known exploits in the wild provides a window for proactive mitigation before widespread attacks occur.

1. Monitor ThimPress official channels for security patches addressing CVE-2025-63012 and apply updates promptly once available. 2. Implement anti-CSRF tokens in all forms and state-changing requests within the WP Hotel Booking plugin or via custom development if patches are delayed. 3. Restrict administrative and booking management access to trusted users only, employing the principle of least privilege. 4. Use web application firewalls (WAFs) with rules designed to detect and block CSRF attack patterns targeting the plugin. 5. Educate users and administrators about the risks of clicking on suspicious links or visiting untrusted websites while authenticated to the booking system. 6. Regularly audit and monitor logs for unusual or unauthorized actions that could indicate exploitation attempts. 7. Consider isolating the booking management system from other critical infrastructure to limit potential lateral movement in case of compromise.
