CVE-2025-49332 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WordPress plugin 'WP Time Slots Booking Form' developed by codepeople. This vulnerability affects versions up to 1.2.30. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged HTTP request to a web application, causing the application to perform unwanted actions on behalf of the user without their consent. In this case, the vulnerability allows an attacker to craft malicious requests that, when executed by an authenticated user, could modify booking form data or settings without proper authorization. The CVSS 3.1 base score is 4.3 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), no impact on confidentiality (C:N), low impact on integrity (I:L), and no impact on availability (A:N). This means the attack can be launched remotely without authentication but requires the victim to interact with a malicious link or webpage. The main impact is limited to integrity, potentially allowing unauthorized changes to booking form data or configurations. No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. The vulnerability is classified under CWE-352, which is a well-known web security weakness related to CSRF attacks. Given the plugin’s role in managing booking slots, exploitation could disrupt scheduling or allow unauthorized modifications, potentially affecting business operations relying on this plugin for appointment or resource management.

For European organizations using the WP Time Slots Booking Form plugin, this vulnerability could lead to unauthorized manipulation of booking data, resulting in scheduling conflicts, denial of service to legitimate users, or reputational damage if customers experience booking errors. While the confidentiality of data is not directly impacted, the integrity of booking information is at risk, which could disrupt business workflows, especially for service providers relying heavily on online booking systems (e.g., healthcare providers, educational institutions, event organizers). The requirement for user interaction reduces the likelihood of widespread automated exploitation but targeted phishing or social engineering campaigns could leverage this vulnerability. Organizations in Europe with high reliance on WordPress-based booking solutions should be aware of potential operational disruptions and customer trust issues stemming from this vulnerability.

Specific mitigation steps include: 1) Immediate review and application of any available updates or patches from the plugin vendor once released. 2) If no patch is available, temporarily disabling or replacing the WP Time Slots Booking Form plugin with alternative booking solutions that implement proper CSRF protections. 3) Implementing Web Application Firewall (WAF) rules to detect and block suspicious CSRF attempts targeting the booking form endpoints. 4) Educating users and administrators about the risks of interacting with untrusted links or emails that could trigger CSRF attacks. 5) Reviewing and hardening WordPress security configurations, including enforcing strict user roles and permissions to limit the impact of any unauthorized actions. 6) Monitoring logs for unusual booking form activity that could indicate exploitation attempts. 7) Employing security headers such as SameSite cookies to reduce CSRF risks where applicable. These measures go beyond generic advice by focusing on plugin-specific controls, user awareness, and layered defenses.
