CVE-2026-115326 in QloApps
Summary
by MITRE • 10/22/2026
QloApps through 1.7.0 contains an insecure direct object reference vulnerability in OrderDetailController::displayAjaxSubmitRefundRequest() that allows authenticated customers to submit refunds for other customers' service lines. Attackers can submit foreign id_service_product_order_detail values with their own id_order to create refund records, cancel victims' service lines, and corrupt refund quantities.

The vulnerability identified in QloApps versions through 1.7.0 represents a critical failure in access control mechanisms within the e-commerce platform's order management subsystem. Specifically located in the OrderDetailController::displayAjaxSubmitRefundRequest() function, this flaw is classified as an Insecure Direct Object Reference (IDOR), which corresponds to CWE-639 in the Common Weakness Enumeration standard. This type of vulnerability arises when a web application uses user-supplied input to access objects directly without verifying that the requester has permission to perform such operations on those specific resources. In this context, the system fails to validate whether the authenticated customer initiating the refund request is the legitimate owner of the service line being refunded or if they have authorization to modify records belonging to other users.
From a technical perspective, the exploitation vector relies on manipulating HTTP parameters during the AJAX submission process for refund requests. An attacker who has successfully authenticated as a valid user can intercept and alter the payload sent to the backend API endpoint responsible for processing refunds. By substituting their own order identifier with an id_service_product_order_detail value that belongs to another customer, while retaining their own id_order or manipulating it further depending on implementation specifics, the application processes the request without cross-referencing ownership constraints. This lack of server-side authorization checks allows the system to generate refund records for transactions that do not belong to the initiating user, effectively bypassing logical access controls designed to isolate customer data and financial operations.
The operational impact of this vulnerability is severe, affecting both the integrity of financial records and the availability of services for legitimate users. Attackers can exploit this flaw to cancel service lines belonging to other customers by submitting fraudulent refund requests that mirror valid cancellation procedures. This action results in the unintended termination or suspension of services for victims who have not requested such changes, leading to potential business disruption and loss of trust. Furthermore, the ability to corrupt refund quantities allows attackers to manipulate financial data within the system's database. This can lead to discrepancies in accounting records, incorrect inventory adjustments if tied to stock levels, and potentially facilitate fraud by creating phantom refunds that drain merchant funds or distort sales analytics.
This vulnerability aligns with several tactics defined in the MITRE ATT&CK framework for enterprise security. It falls under the Initial Access category as it requires authentication but exploits a logical flaw rather than a technical breach of credentials. More critically, it maps to Defense Evasion and Impact techniques where an attacker manipulates system state to hide malicious activity or cause damage. The specific behavior of modifying resources belonging to other users is characteristic of horizontal privilege escalation within the application's logic layer. Security professionals should note that this is not merely a data leakage issue but an active integrity violation capable of causing tangible harm to business operations and customer relationships.
Mitigation strategies must focus on implementing robust server-side authorization checks for all sensitive operations involving user-specific resources. Developers need to ensure that every request modifying or accessing order details verifies that the authenticated session's user ID matches the owner ID associated with the target resource, such as id_service_product_order_detail. Implementing strict input validation and ensuring that foreign keys are validated against ownership records before processing any refund logic is essential. Additionally, adopting a principle of least privilege for API endpoints can help limit the scope of actions available to authenticated users. Regular security audits focusing on business logic flaws and implementing automated testing for IDOR vulnerabilities during the development lifecycle will further reduce the risk of such exploitations in future releases.
