CVE-2026-24367 identifies a Blind SQL Injection vulnerability in the shinetheme Traveler product, affecting all versions before 3.2.8. The vulnerability arises from improper neutralization of special elements in SQL commands, allowing attackers to inject malicious SQL code. Blind SQL Injection means attackers cannot directly see query results but can infer data through response behaviors or timing, enabling extraction of sensitive information or manipulation of the database. The CVSS 3.1 score of 8.8 reflects a high-severity issue with network attack vector (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H). Exploitation can lead to unauthorized data disclosure, data tampering, or service disruption. Although no public exploits are known, the vulnerability's nature and ease of exploitation make it a critical concern. The affected product is used primarily in travel-related applications, which often handle personal and payment data, increasing the risk profile. The lack of available patches at the time of disclosure necessitates immediate attention to mitigation strategies.

For European organizations, this vulnerability poses a significant threat to data security and service continuity. Travel and hospitality sectors, which frequently use shinetheme Traveler, may face data breaches exposing personal customer information, including payment details and travel itineraries. This can lead to regulatory penalties under GDPR for data protection failures, reputational damage, and financial losses. Additionally, attackers could alter or delete critical booking or operational data, disrupting services and causing operational downtime. The high severity and ease of exploitation increase the likelihood of targeted attacks, especially against organizations with lower security maturity or delayed patching processes. The impact extends beyond individual companies to the broader travel ecosystem, potentially affecting supply chains and partner networks within Europe.

1. Immediately upgrade shinetheme Traveler to version 3.2.8 or later once available to apply the official patch. 2. Until patching is possible, implement strict input validation and sanitization on all user-supplied data fields interacting with SQL queries to block injection attempts. 3. Employ web application firewalls (WAFs) configured to detect and block SQL injection patterns, including blind injection techniques. 4. Monitor database query logs and application behavior for anomalies indicative of injection attempts or unauthorized access. 5. Restrict database user privileges to the minimum necessary to limit the impact of potential exploitation. 6. Conduct security audits and penetration testing focused on injection vulnerabilities in the Traveler deployment. 7. Educate development and operations teams about secure coding practices and the risks of SQL injection. 8. Ensure incident response plans are updated to address potential exploitation scenarios involving this vulnerability.
