CVE-2025-13115 is an improper authorization vulnerability identified in the macrozheng mall-swarm e-commerce platform, specifically affecting versions 1.0.0 through 1.0.3. The flaw resides in the /order/detail/ endpoint within the Order Details Handler component, where the orderId parameter is insufficiently validated. This allows remote attackers to manipulate the orderId argument to retrieve order details without proper authorization. The vulnerability does not require authentication or user interaction, making it remotely exploitable over the network. The vendor was notified but has not issued any patches or advisories. The vulnerability has a CVSS 4.0 base score of 5.3, indicating a medium severity level. The exploit code has been publicly released, increasing the risk of exploitation. The lack of proper access control could lead to unauthorized disclosure of sensitive customer order information, potentially exposing personal data and transaction details. This could facilitate further attacks such as identity theft, fraud, or competitive intelligence gathering. The vulnerability affects all known versions up to 1.0.3, and no mitigations or patches are currently available from the vendor. Organizations using mall-swarm should assume exposure and take immediate compensating controls.

For European organizations, this vulnerability poses a risk of unauthorized access to sensitive order information, potentially including customer identities, purchase histories, and payment details. This could lead to violations of GDPR requirements regarding data confidentiality and protection, resulting in regulatory penalties and reputational damage. E-commerce businesses relying on mall-swarm for order management may face customer trust erosion and financial losses if attackers exploit this flaw to harvest or manipulate order data. The exposure of order details can also facilitate targeted phishing or social engineering attacks. Since the vulnerability requires no authentication and can be exploited remotely, the attack surface is broad, increasing the likelihood of exploitation. The absence of vendor patches means organizations must rely on internal controls and monitoring to mitigate risk. Overall, the impact includes data confidentiality breaches, potential compliance violations, and operational disruptions in order processing workflows.

Given the lack of official patches, European organizations should implement strict server-side authorization checks to validate that the requesting user is authorized to access the specified orderId. This can be done by enforcing user identity verification against order ownership before returning order details. Web application firewalls (WAFs) should be configured to detect and block anomalous requests manipulating the orderId parameter, such as requests accessing orders not belonging to the authenticated user or originating from suspicious IP addresses. Logging and monitoring should be enhanced to detect unusual access patterns to the /order/detail/ endpoint. Organizations should consider isolating the vulnerable component behind additional access controls or network segmentation to limit exposure. If feasible, temporarily disabling or restricting access to the order detail functionality until a patch is available can reduce risk. Finally, organizations should prepare incident response plans to address potential data breaches resulting from exploitation.
