CVE-2025-13115 is an authorization vulnerability affecting macrozheng's mall-swarm and mall products up to version 1.0.3. The vulnerability resides in the Order Details Handler component, specifically in the /order/detail/ endpoint, where the orderId parameter is insufficiently validated. This improper authorization allows remote attackers to manipulate the orderId argument to access order details that they should not be authorized to view. The vulnerability does not require authentication or user interaction, making it remotely exploitable over the network with low attack complexity. The CVSS 4.0 score is 5.3 (medium), reflecting a partial confidentiality impact with no integrity or availability effects. The vendor was notified but has not issued any patches or responses. Public exploit code is available, increasing the likelihood of exploitation. This vulnerability could lead to unauthorized disclosure of sensitive order information, potentially exposing customer data and transaction details. The lack of vendor response and patch availability increases the urgency for organizations to implement compensating controls. The flaw highlights the importance of robust access control mechanisms in e-commerce platforms to prevent unauthorized data access.

For European organizations, the primary impact is unauthorized disclosure of order-related data, which may include customer personal information, purchase history, and potentially payment details if stored within order records. This can lead to privacy violations under GDPR, reputational damage, and potential regulatory fines. While the vulnerability does not allow modification or deletion of data, the confidentiality breach alone is significant for businesses handling sensitive customer information. Retailers and online marketplaces using macrozheng mall-swarm could see targeted exploitation attempts, especially given the public availability of exploits. The medium severity rating indicates moderate risk, but the ease of exploitation and lack of authentication requirements elevate concerns. Organizations may also face increased phishing or social engineering attacks leveraging leaked order data. The absence of vendor patches means organizations must rely on internal mitigations, increasing operational overhead. Overall, this vulnerability threatens customer trust and compliance posture for European e-commerce entities.

1. Immediately implement strict server-side authorization checks on the /order/detail/ endpoint to validate that the requesting user is authorized to access the specified orderId. 2. Employ parameter validation and enforce access control policies that tie orderId access to authenticated user identities or roles. 3. Monitor web server logs and application logs for anomalous or repeated access attempts to /order/detail/ with varying orderId values indicative of enumeration or exploitation attempts. 4. If possible, restrict access to the order detail API endpoint to authenticated users only, even if the original design allowed unauthenticated access. 5. Use Web Application Firewalls (WAFs) with custom rules to detect and block suspicious manipulation of orderId parameters. 6. Conduct a thorough review of all endpoints handling sensitive data for similar authorization weaknesses. 7. Prepare incident response plans for potential data leakage scenarios and notify affected customers if breaches occur. 8. Engage with the vendor or consider migrating to alternative e-commerce platforms with better security support if no patches are forthcoming. 9. Regularly update and audit access control mechanisms as part of secure software development lifecycle practices.
