CVE-2025-64371 is a security vulnerability classified as Blind SQL Injection found in the shinetheme Traveler product, affecting versions prior to 3.2.6. The root cause is improper neutralization of special elements used in SQL commands, allowing attackers to craft malicious input that alters the intended SQL query logic. Blind SQL Injection differs from classic SQL Injection in that it does not directly return database errors or data, but attackers can infer information by observing application behavior or response times. This vulnerability can be exploited remotely without authentication or user interaction, making it a significant risk. Exploitation could enable attackers to extract sensitive data, modify or delete records, or escalate privileges within the database backend. Although no public exploits are currently known, the vulnerability's presence in a widely used theme for travel-related websites could attract attackers targeting tourism, hospitality, or booking platforms. The lack of a CVSS score indicates the need for severity assessment based on impact and exploitability factors. The vulnerability was reserved in late 2025 and published shortly thereafter, with no patches currently linked, highlighting the importance of monitoring vendor updates. The technical details emphasize the need for input sanitization and secure coding practices to prevent injection flaws.

For European organizations, particularly those in the travel, tourism, and hospitality sectors that utilize the shinetheme Traveler product, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive customer and business data. Successful exploitation could lead to unauthorized access to booking information, personal customer data, or financial records, potentially resulting in data breaches and regulatory non-compliance under GDPR. The disruption or manipulation of backend databases could also impact availability indirectly by corrupting data or causing application errors. Given the remote and unauthenticated nature of the exploit, attackers could operate stealthily, increasing the risk of prolonged undetected compromise. The reputational damage and financial losses from such incidents could be substantial, especially for organizations heavily reliant on online booking systems. Additionally, the vulnerability could be leveraged as a foothold for further network intrusion or lateral movement within affected organizations.

Immediate mitigation should focus on applying official patches from shinetheme once they become available for Traveler versions prior to 3.2.6. Until patches are released, organizations should implement strict input validation and sanitization on all user-supplied data fields interacting with the database. Deploying a web application firewall (WAF) with rules specifically designed to detect and block SQL injection attempts can provide an effective interim defense. Conduct thorough code reviews and penetration testing to identify and remediate injection points. Restrict database user permissions to the minimum necessary to limit the impact of potential exploitation. Enable detailed logging and monitoring of database queries and application behavior to detect anomalous activity indicative of exploitation attempts. Educate development and security teams on secure coding practices to prevent similar vulnerabilities in future releases. Lastly, maintain an incident response plan tailored to SQL injection attacks to ensure rapid containment and recovery if exploitation occurs.
