CVE-2025-63013 is a security vulnerability identified in the ThimPress WP Hotel Booking plugin for WordPress, affecting versions up to and including 2.2.7. The vulnerability involves the exposure of sensitive system information to unauthorized users, classified as an 'Exposure of Sensitive System Information to an Unauthorized Control Sphere.' This means that attackers can retrieve embedded sensitive data from the plugin without proper authorization. The exact nature of the sensitive data is not detailed, but such information typically includes configuration details, system paths, or credentials that can facilitate further attacks. The vulnerability was reserved on October 24, 2025, and published on December 9, 2025, but no CVSS score has been assigned yet, and no known exploits have been reported in the wild. The plugin is widely used by hospitality businesses to manage hotel bookings on WordPress sites, making it a valuable target for attackers seeking to gain insights into system configurations or customer data. The lack of authentication requirements to exploit this vulnerability increases its risk profile. Since no patch links are currently available, users must monitor vendor communications for updates. The vulnerability's presence in a popular WordPress plugin underscores the importance of plugin security hygiene and timely updates in the WordPress ecosystem.

For European organizations, especially those in the hospitality and tourism sectors relying on the WP Hotel Booking plugin, this vulnerability poses a significant risk of sensitive data exposure. The leaked information could include system configurations or embedded credentials, which attackers might leverage to escalate privileges, conduct targeted attacks, or compromise customer data confidentiality. This could lead to reputational damage, regulatory penalties under GDPR for data breaches, and operational disruptions. Since the hospitality industry is a prime target for cybercriminals due to the volume of personal and payment data processed, the impact is amplified. Additionally, unauthorized access to system information can facilitate lateral movement within networks, increasing the risk of broader compromise. The absence of known exploits currently provides a window for mitigation, but the ease of exploitation without authentication means that attackers could quickly develop and deploy exploits, increasing urgency for affected organizations.

1. Immediately inventory all WordPress installations to identify those running WP Hotel Booking plugin versions up to 2.2.7. 2. Monitor official ThimPress channels and Patchstack for patch releases addressing CVE-2025-63013 and apply updates promptly once available. 3. Until patches are released, restrict access to plugin-related endpoints using web application firewalls (WAFs) or server-level access controls to prevent unauthorized retrieval of sensitive data. 4. Implement strict role-based access controls within WordPress to limit plugin management capabilities to trusted administrators. 5. Conduct thorough security audits and log monitoring to detect any suspicious access attempts targeting the plugin. 6. Educate IT and security teams about the vulnerability to ensure rapid response and containment. 7. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect anomalous requests to the WP Hotel Booking plugin. 8. Regularly back up WordPress sites and configurations to enable quick recovery in case of compromise. 9. Review and harden WordPress security configurations, including disabling unnecessary plugin features that may expose data. 10. Engage with cybersecurity vendors or services specializing in WordPress security for advanced protection and monitoring.
