CVE-2025-22634 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Easy Booked – Appointment Booking and Scheduling Management System plugin for WordPress, developed by MD Abu Jubayer Hossain. The affected versions include all releases up to and including 2.4.5. CSRF vulnerabilities occur when a web application does not properly verify that requests made to it originate from authenticated and authorized users, allowing attackers to craft malicious requests that execute actions on behalf of logged-in users without their knowledge. In this case, the Easy Booked plugin lacks sufficient CSRF protections, enabling attackers to potentially manipulate appointment bookings or scheduling data by tricking authenticated users into visiting malicious websites or clicking crafted links. The vulnerability does not require the attacker to have direct authentication credentials but does require the victim to be logged into the vulnerable WordPress site. No CVSS score has been assigned yet, and no public exploits have been reported. However, the nature of the vulnerability means it could be leveraged to alter or delete booking information, disrupt service availability, or cause unauthorized changes to scheduling data, impacting business operations that rely on this plugin. The vulnerability was reserved in January 2025 and published in March 2025, indicating recent discovery and disclosure. The plugin is widely used in WordPress environments for appointment management, making the attack surface significant in sectors relying on online scheduling.

The primary impact of this CSRF vulnerability is on the integrity and availability of appointment and scheduling data managed by the Easy Booked plugin. Attackers could manipulate bookings, cancel appointments, or alter scheduling details without authorization, leading to operational disruptions, loss of customer trust, and potential financial losses for organizations relying on accurate scheduling. Confidentiality impact is limited as the vulnerability does not directly expose sensitive data but could be combined with other vulnerabilities for broader compromise. The ease of exploitation is relatively high since it only requires the victim to be authenticated and visit a malicious page, with no additional authentication or user interaction needed beyond that. Organizations worldwide using this plugin in healthcare, education, professional services, or any sector relying on appointment scheduling are at risk. The disruption could affect customer service quality and damage organizational reputation. Although no known exploits are currently active, the vulnerability's presence in a widely used WordPress plugin increases the likelihood of future exploitation attempts.

To mitigate CVE-2025-22634, organizations should immediately update the Easy Booked plugin to a version that includes a fix once released by the vendor. Until a patch is available, implement the following specific measures: 1) Employ Web Application Firewalls (WAFs) with rules to detect and block CSRF attack patterns targeting the plugin's endpoints. 2) Restrict access to the WordPress admin interface and plugin functionalities to trusted IP addresses or VPNs to reduce exposure. 3) Enforce strict session management and ensure users log out after use to minimize the window of opportunity for CSRF attacks. 4) Use security plugins that add CSRF tokens to forms and verify them on submission, or manually add nonce verification in plugin code if feasible. 5) Educate users about the risks of clicking unknown links while logged into administrative accounts. 6) Monitor logs for unusual POST requests or changes in booking data that could indicate exploitation attempts. These targeted actions go beyond generic advice by focusing on the plugin’s specific attack surface and operational context.
