CVE-2026-0585 identifies a SQL injection vulnerability in the Online Product Reservation System version 1.0 developed by code-projects. The vulnerability is located in the /order_view.php file within the GET parameter handler for the transaction_id argument. An attacker can remotely inject malicious SQL code by manipulating this parameter, which the application fails to properly sanitize or parameterize before executing database queries. This can lead to unauthorized disclosure, modification, or deletion of data stored in the backend database. The attack requires no authentication or user interaction and can be performed over the network, increasing its risk profile. The CVSS 4.0 vector indicates low complexity and no privileges required, but the impact on confidentiality, integrity, and availability is limited, resulting in a medium severity rating with a score of 6.9. Although no public exploits have been observed in the wild, the public disclosure of the vulnerability increases the likelihood of exploitation attempts. The lack of available patches necessitates immediate remediation efforts by organizations using this software. The vulnerability primarily affects the database layer and could compromise sensitive customer or transaction data, impacting business operations and regulatory compliance.

For European organizations, exploitation of CVE-2026-0585 could result in unauthorized access to sensitive customer and transaction data, leading to potential data breaches and loss of customer trust. This is particularly critical for companies in retail, e-commerce, and reservation services that rely on the affected Online Product Reservation System. Data integrity could be compromised, allowing attackers to alter or delete reservation records, which may disrupt business operations and cause financial losses. Additionally, organizations may face regulatory penalties under GDPR for failing to protect personal data adequately. The remote and unauthenticated nature of the attack vector increases the risk of widespread exploitation, especially if the vulnerability is leveraged in automated attacks or combined with other threats. Although the impact on availability is limited, the reputational damage and operational disruptions could be significant. European entities with limited cybersecurity resources may find it challenging to detect and respond to exploitation attempts promptly.

Organizations should immediately audit their use of the code-projects Online Product Reservation System version 1.0 and identify any exposed instances of /order_view.php handling the transaction_id parameter. Since no official patches are currently available, developers must implement input validation and sanitize all user-supplied parameters rigorously. The best practice is to refactor the vulnerable code to use parameterized queries or prepared statements to prevent SQL injection. Additionally, web application firewalls (WAFs) should be configured to detect and block suspicious SQL injection patterns targeting the transaction_id parameter. Network segmentation and restricting access to the affected application endpoints can reduce exposure. Continuous monitoring of logs for unusual database queries or errors related to transaction_id can help detect exploitation attempts early. Organizations should also prepare incident response plans specific to SQL injection attacks and consider engaging with cybersecurity professionals to perform penetration testing and code reviews. Finally, maintaining up-to-date backups of critical data will aid recovery in case of data manipulation or loss.
