CVE-2025-49378 identifies a critical SQL Injection vulnerability in the Themefic Hydra Booking plugin, a WordPress-based booking management system widely used for scheduling appointments and events. The vulnerability arises from improper neutralization of special characters in SQL commands, allowing attackers to inject arbitrary SQL code. This can lead to unauthorized data retrieval, modification, or deletion within the backend database. The affected versions include all releases up to and including 1.1.10. Although no public exploits have been reported yet, the nature of SQL Injection vulnerabilities makes them attractive targets for attackers seeking to compromise confidentiality, integrity, and availability of data. The vulnerability does not require prior authentication, increasing the risk of exploitation by remote attackers. Since no CVSS score is assigned, the severity is inferred from the potential impact on data security and system stability. The absence of official patches at the time of publication necessitates interim mitigations such as input sanitization and deployment of web application firewalls. The plugin’s usage in sectors handling personal and financial data amplifies the threat, especially in regions with high digital service adoption. Monitoring for anomalous database queries and timely patching upon vendor release are critical to mitigating this vulnerability.

For European organizations, exploitation of this SQL Injection vulnerability could result in unauthorized access to sensitive customer and business data, including personal information and booking details. This could lead to data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and financial losses. Additionally, attackers might alter or delete booking records, disrupting business operations and customer trust. The vulnerability's ease of exploitation without authentication increases the risk of widespread attacks, particularly targeting service industries such as hospitality, healthcare, and event management that rely heavily on booking systems. The potential for lateral movement within compromised networks could further escalate the impact. Organizations may also face legal and regulatory consequences if personal data is exposed or manipulated. Overall, the threat poses a significant risk to data confidentiality, integrity, and availability within European digital service ecosystems.

1. Monitor Themefic’s official channels closely for security patches addressing CVE-2025-49378 and apply them immediately upon release. 2. Implement strict input validation and sanitization on all user-supplied data fields related to the booking plugin to prevent injection of malicious SQL code. 3. Deploy a Web Application Firewall (WAF) configured to detect and block SQL Injection attempts targeting the Hydra Booking plugin. 4. Conduct regular security assessments and vulnerability scans focusing on WordPress plugins, especially those handling sensitive data. 5. Restrict database user permissions to the minimum necessary for the plugin’s operation, limiting the potential damage from successful injection attacks. 6. Enable detailed logging and monitoring of database queries and application logs to detect unusual or suspicious activity promptly. 7. Educate IT and security teams about the risks associated with SQL Injection and the specific threat posed by this vulnerability. 8. Consider temporary disabling or replacing the Hydra Booking plugin with a more secure alternative if immediate patching is not feasible.
