CVE-2026-22481 identifies a missing authorization vulnerability in the BD Courier Order Ratio Checker, a tool developed by Rasedul Haque Rumi used to analyze courier order ratios. The vulnerability arises from incorrectly configured access control mechanisms that fail to properly verify user privileges before granting access to sensitive functions. This allows attackers with limited privileges (PR:L) to escalate their access rights without requiring user interaction (UI:N), potentially leading to unauthorized data access, modification, or disruption of service. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) indicates network exploitable, low attack complexity, and high impact on confidentiality, integrity, and availability. The affected versions include all up to 2.0.1, with no patches currently listed. Although no exploits have been observed in the wild, the vulnerability’s nature suggests that attackers could leverage it to gain full control over the affected system or extract sensitive courier data, impacting operational reliability and data privacy. The issue is critical for organizations relying on this software for logistics analytics and operational decision-making.

For European organizations, particularly those in the logistics, courier, and supply chain sectors, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive shipment and order data, manipulation of courier order ratios, and disruption of service availability, potentially causing operational delays and financial losses. Confidentiality breaches could expose customer data and business intelligence, undermining trust and compliance with GDPR. Integrity violations may distort courier metrics, leading to flawed business decisions. Availability impacts could halt courier operations, affecting delivery timelines and customer satisfaction. Given the interconnected nature of European supply chains, a successful attack could have cascading effects across multiple countries and industries. Organizations using this software must assess exposure and implement controls to prevent exploitation.

1. Immediately restrict access to the BD Courier Order Ratio Checker to trusted administrators and limit user privileges to the minimum necessary. 2. Implement network segmentation to isolate the affected system from critical infrastructure and sensitive data repositories. 3. Monitor logs and network traffic for unusual access patterns or privilege escalations related to the software. 4. Apply strict authentication and authorization controls, including multi-factor authentication for privileged accounts. 5. Since no official patches are currently available, consider deploying web application firewalls (WAFs) with custom rules to block unauthorized access attempts targeting this vulnerability. 6. Engage with the vendor or developer to obtain patches or updates as soon as they are released. 7. Conduct regular security assessments and penetration testing focused on access control mechanisms within the software. 8. Educate staff about the risks and signs of exploitation attempts to enhance detection and response capabilities.
