CVE-2025-13114 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 updateAttr function of the /cart/update/attr endpoint, which handles updates to cart attributes. Due to insufficient authorization checks, remote attackers can invoke this function without proper privileges, enabling unauthorized manipulation of cart data. This can lead to unauthorized changes in shopping cart attributes, potentially affecting order integrity, pricing, or inventory management. The vulnerability does not require authentication or user interaction, making it easier to exploit remotely. The CVSS 4.0 base score is 5.3 (medium severity), reflecting low complexity and no privileges required, but limited impact on confidentiality, integrity, and availability. The vendor was notified early but has not responded or provided patches, and while public exploit code exists, no active exploitation has been reported. This vulnerability highlights risks in e-commerce platforms where improper authorization can undermine transaction integrity and customer trust. Organizations using mall-swarm should be aware of this exposure and take immediate protective actions.

For European organizations, especially those operating e-commerce platforms using macrozheng mall-swarm, this vulnerability poses risks to transaction integrity and operational continuity. Unauthorized attackers could manipulate cart attributes, potentially altering order details, pricing, or inventory data, leading to financial losses, customer dissatisfaction, or supply chain disruptions. Although the vulnerability does not directly expose sensitive personal data, the integrity compromise could facilitate fraud or denial of service conditions. The lack of vendor response and patches increases exposure duration, raising the likelihood of exploitation once attackers integrate the public exploit code into their toolsets. Organizations relying on mall-swarm for critical sales channels may experience reputational damage and regulatory scrutiny if customer transactions are compromised. The medium severity suggests moderate urgency, but the ease of exploitation and remote attack vector warrant prompt attention. European data protection regulations emphasize integrity and availability, so exploitation could have compliance implications as well.

Since no official patches are currently available, European organizations should implement compensating controls immediately. These include: 1) Restrict network access to the /cart/update/attr endpoint using web application firewalls (WAFs) or network segmentation to limit exposure to trusted IPs or internal networks. 2) Implement strict access control policies at the application layer, adding custom authorization checks to validate user privileges before allowing attribute updates. 3) Monitor logs and network traffic for unusual or unauthorized requests targeting the vulnerable endpoint, enabling rapid detection of exploitation attempts. 4) Employ rate limiting and anomaly detection to reduce the risk of automated attacks leveraging the public exploit. 5) Isolate or temporarily disable vulnerable mall-swarm instances if feasible until vendor patches are released. 6) Engage with the vendor or community to track patch availability and apply updates promptly once released. 7) Conduct security awareness training for developers and administrators on secure authorization practices to prevent similar issues in future deployments.
