CVE-2025-49378 is an SQL Injection vulnerability identified in Themefic Hydra Booking, a WordPress plugin used for managing bookings and reservations. The vulnerability stems from improper neutralization of special characters in SQL commands, enabling attackers to inject malicious SQL code. This flaw affects all versions up to and including 1.1.10. The vulnerability allows remote attackers with low privileges to execute arbitrary SQL queries on the backend database without requiring user interaction, though the attack complexity is rated high, indicating some non-trivial conditions must be met for successful exploitation. The impact is severe, as attackers can compromise the confidentiality, integrity, and availability of the system by extracting sensitive data, modifying or deleting records, or causing denial of service. No known exploits have been reported in the wild, and no official patches have been published at the time of disclosure. The vulnerability was reserved in June 2025 and published in October 2025. The CVSS v3.1 score is 8.5, reflecting high severity with network attack vector, low privileges required, no user interaction, and a scope change. The vulnerability is critical for organizations relying on Hydra Booking for customer reservations, as it can lead to data breaches and operational disruption.

For European organizations, this vulnerability poses significant risks, especially for those in hospitality, event management, and service industries that utilize Hydra Booking for online reservations. Exploitation could lead to unauthorized access to customer data, including personally identifiable information (PII), booking details, and payment information, violating GDPR and other data protection regulations. Integrity of booking data could be compromised, leading to fraudulent bookings or cancellations, damaging business reputation and customer trust. Availability impacts could disrupt booking services, causing operational downtime and financial losses. The high severity and scope change mean that even low-privileged attackers can escalate their impact, increasing the threat landscape. Organizations with internet-facing booking systems are particularly vulnerable to remote exploitation attempts. The absence of known exploits offers a window for proactive mitigation, but the lack of patches necessitates immediate defensive measures.

1. Monitor Themefic’s official channels for security patches addressing CVE-2025-49378 and apply updates promptly once available. 2. Implement Web Application Firewalls (WAFs) with robust SQL Injection detection and prevention rules tailored to block malicious payloads targeting Hydra Booking. 3. Conduct thorough input validation and sanitization on all user-supplied data, especially parameters involved in database queries. 4. Restrict database user permissions to the minimum necessary, avoiding elevated privileges that could amplify damage if exploited. 5. Employ network segmentation to isolate booking systems from critical internal resources. 6. Regularly audit and monitor logs for suspicious SQL query patterns or anomalies indicative of injection attempts. 7. Consider temporary mitigation by disabling or restricting access to vulnerable plugin features until patches are available. 8. Educate IT and security teams about the vulnerability specifics to enhance detection and response capabilities. 9. Perform penetration testing focused on SQL Injection vectors to identify and remediate similar weaknesses in the environment.
