CVE-2025-13443 is a vulnerability identified in the macrozheng mall e-commerce platform, specifically affecting versions 1.0.0 through 1.0.3. The issue resides in the delete function located at the endpoint /member/readHistory/delete. This function accepts an argument named 'ids' which is intended to specify which user read history records to delete. Due to improper access control checks, an attacker can manipulate this argument to delete read history records belonging to other users without proper authorization. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, making it accessible to unauthenticated attackers. The CVSS 4.0 vector indicates low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and partial impact on integrity and availability (VI:L, VA:L). Although no exploits have been observed in the wild, a public exploit is available, increasing the risk of exploitation. The vulnerability primarily threatens data integrity by allowing unauthorized deletion of user data, which could disrupt user experience and trust in the platform. The lack of proper access control suggests a design or implementation flaw in the authorization logic of the affected endpoint. No official patches have been linked yet, indicating that organizations must be vigilant and consider interim mitigations. This vulnerability highlights the critical importance of enforcing strict access control on sensitive operations in web applications, especially those handling user data in e-commerce environments.

For European organizations using macrozheng mall, this vulnerability poses a risk of unauthorized data modification, specifically the deletion of user read history data. While it does not directly expose sensitive personal data, the ability to alter or delete user activity records can undermine data integrity and user trust, potentially affecting compliance with data protection regulations such as GDPR. Disruption of user data could impact customer experience and operational continuity, especially for businesses relying on read history for personalized services or analytics. The remote and unauthenticated nature of the exploit increases the attack surface, making it easier for threat actors to target vulnerable installations. Although the vulnerability does not lead to full system compromise or data leakage, the integrity and availability impacts could facilitate further attacks or fraud. European e-commerce platforms are particularly sensitive to reputational damage and regulatory scrutiny, so even moderate-impact vulnerabilities require prompt attention. The absence of known exploits in the wild currently reduces immediate risk but the public availability of an exploit increases the likelihood of future attacks.

1. Monitor macrozheng mall vendor communications closely for official patches addressing CVE-2025-13443 and apply them promptly once available. 2. Until patches are released, implement strict access control rules at the web application firewall (WAF) or reverse proxy level to restrict access to the /member/readHistory/delete endpoint only to authenticated and authorized users. 3. Conduct a thorough review of authorization logic in the application code, ensuring that user identity is properly verified before allowing deletion operations. 4. Implement detailed logging and monitoring of deletion requests, focusing on unusual patterns such as bulk deletions or requests from unexpected IP addresses. 5. Educate development and security teams about the risks of improper access controls and enforce secure coding practices to prevent similar vulnerabilities. 6. Consider deploying runtime application self-protection (RASP) tools to detect and block unauthorized access attempts in real time. 7. Regularly audit user permissions and roles to minimize privilege escalation risks. 8. If feasible, isolate the affected service or limit its exposure to internal networks until a fix is applied. 9. Engage in threat intelligence sharing with industry peers to stay informed about emerging exploitation trends related to this vulnerability.
