CVE-2025-52714 is a critical SQL Injection vulnerability (CWE-89) found in the shinetheme Traveler product. SQL Injection vulnerabilities occur when user-supplied input is improperly sanitized or neutralized before being incorporated into SQL queries, allowing attackers to manipulate the database queries executed by the application. In this case, the vulnerability allows an unauthenticated attacker with network access to the affected system to inject malicious SQL commands. The CVSS 3.1 base score of 9.3 reflects the high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. The impact on confidentiality is high (C:H), while integrity is not impacted (I:N), and availability impact is low (A:L). This suggests that an attacker could extract sensitive data from the backend database but may not be able to modify or delete data or cause significant denial of service. The vulnerability affects the Traveler product from shinetheme, although specific affected versions are not provided. No patches or known exploits in the wild are currently reported. Given the nature of SQL Injection, exploitation could lead to unauthorized data disclosure, potentially exposing sensitive user or business information stored in the database. The lack of authentication requirement and network accessibility makes this vulnerability particularly dangerous, as it can be exploited remotely without credentials or user interaction. The changed scope indicates that the attacker might leverage the vulnerability to access or affect other components or data beyond the immediate application context.

For European organizations using the shinetheme Traveler product, this vulnerability poses a significant risk of data breaches, especially if the application handles personal data, financial information, or other sensitive records protected under regulations such as GDPR. Unauthorized disclosure of such data could lead to regulatory penalties, reputational damage, and loss of customer trust. The ability to exploit this vulnerability remotely without authentication increases the attack surface and likelihood of exploitation. Additionally, the changed scope impact means that attackers might pivot to other internal systems or escalate their access, potentially leading to broader compromise within an organization's network. Organizations in sectors such as travel, hospitality, or any industry relying on the Traveler product for booking or customer management are particularly at risk. The low availability impact suggests that service disruption is less likely, but data confidentiality breaches remain a critical concern.

Given the absence of official patches, European organizations should immediately conduct a thorough inventory to identify deployments of the shinetheme Traveler product. Until patches are available, organizations should implement strict network-level access controls, such as firewall rules or web application firewalls (WAFs), to restrict external access to the vulnerable application interfaces. Employing WAFs with SQL Injection detection and prevention capabilities can help block malicious payloads targeting this vulnerability. Additionally, organizations should review and harden database permissions to ensure that the application uses least privilege principles, limiting the potential damage from SQL Injection exploitation. Monitoring and logging database queries and application logs for anomalous activity indicative of SQL Injection attempts is critical for early detection. If feasible, temporarily disabling or isolating the vulnerable components until a patch is released can reduce exposure. Finally, organizations should prepare to apply patches promptly once they become available and conduct penetration testing to verify the effectiveness of mitigations.
