CVE-2025-63012 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WP Hotel Booking plugin developed by ThimPress, affecting all versions up to and including 2.2.7. CSRF vulnerabilities enable attackers to induce authenticated users to perform actions they did not intend, by exploiting the trust a web application places in the user's browser. In this case, an attacker could craft malicious web requests that, when executed by an authenticated administrator or user with sufficient privileges, could alter booking information, modify settings, or perform other sensitive operations within the WP Hotel Booking plugin. The vulnerability arises from the absence or improper implementation of anti-CSRF tokens in critical state-changing requests. No CVSS score has been assigned yet, and no public exploits have been reported, but the flaw is publicly disclosed and considered exploitable. The attack does not require the attacker to have direct access to the victim's credentials but does require the victim to be authenticated and to visit a maliciously crafted webpage or link. This vulnerability impacts the integrity and availability of the booking system and potentially the confidentiality of user data if bookings or customer details are manipulated. The plugin is widely used in WordPress-based hotel and accommodation booking websites, which are common in the European hospitality sector. The lack of a patch link suggests that a fix may not yet be available, increasing the urgency for mitigation measures.

For European organizations, particularly those in the hospitality and tourism sectors relying on WordPress and the WP Hotel Booking plugin, this vulnerability poses significant risks. Attackers could manipulate booking data, causing financial loss, reputational damage, and operational disruption. Unauthorized changes could lead to double bookings, cancellations, or exposure of customer information, impacting data confidentiality and integrity. The availability of booking services could also be affected if attackers disrupt normal operations. Given the importance of tourism in countries like Germany, France, Italy, Spain, and the UK, the impact could be widespread. Additionally, regulatory compliance risks arise under GDPR if customer data is compromised or mishandled. The absence of known exploits currently reduces immediate risk but does not eliminate the threat, as attackers often develop exploits after public disclosure. The ease of exploitation via social engineering (e.g., phishing links) and the requirement for victim authentication increase the threat level for organizations with less stringent access controls or user awareness.

Organizations should immediately audit their use of the WP Hotel Booking plugin and identify affected versions (<= 2.2.7). Until an official patch is released, implement the following mitigations: 1) Restrict administrative and booking management access to trusted users only and enforce strong authentication mechanisms such as multi-factor authentication (MFA). 2) Educate users about phishing and social engineering risks to reduce the likelihood of clicking malicious links. 3) Employ web application firewalls (WAFs) with rules to detect and block suspicious CSRF attack patterns targeting the plugin's endpoints. 4) If possible, disable or limit functionalities that perform state-changing operations via GET requests or without CSRF tokens. 5) Monitor logs for unusual activity related to booking changes or administrative actions. 6) Regularly check for and apply updates from ThimPress as soon as patches become available. 7) Consider isolating the booking system or using additional security plugins that enforce CSRF protections. These steps go beyond generic advice by focusing on access control, user awareness, and proactive monitoring tailored to this plugin's context.
