CVE-2025-14016 is an improper authorization vulnerability identified in the macrozheng mall-swarm e-commerce platform, affecting all versions up to 1.0.3. The vulnerability resides in the delete function located at the endpoint /member/readHistory/delete. Specifically, the flaw arises from insufficient authorization validation when processing the 'ids' parameter, which controls which user read history records are deleted. An attacker can remotely manipulate this parameter to delete arbitrary read history entries without proper permissions. The vulnerability does not require authentication or user interaction, making it remotely exploitable over the network with low attack complexity. The vendor was contacted early but has not issued any patch or mitigation guidance. Although no active exploitation in the wild has been reported, public exploit details have been disclosed, increasing the risk of future attacks. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the moderate impact on confidentiality, integrity, and availability, with no privileges or user interaction required. This vulnerability primarily threatens data integrity and availability by enabling unauthorized deletion of user data, potentially disrupting user experience and trust in affected e-commerce platforms.

For European organizations using macrozheng mall-swarm, this vulnerability poses a risk of unauthorized data deletion, which can lead to loss of critical user read history data and degrade service reliability. This could affect customer trust and operational continuity, especially for e-commerce businesses relying on accurate user activity records for personalization, analytics, or compliance purposes. The unauthorized deletion could also be leveraged as part of a larger attack to disrupt services or cover tracks after other malicious activities. Since the vulnerability is remotely exploitable without authentication, it increases the attack surface and risk of automated exploitation attempts. The lack of vendor response and patch availability further exacerbates the risk, potentially leading to prolonged exposure. Organizations may face regulatory scrutiny under GDPR if personal data integrity or availability is compromised. The impact is more pronounced for businesses with high dependency on mall-swarm for customer interaction and data management.

1. Immediately implement strict access control and authorization checks on the /member/readHistory/delete endpoint to ensure only authorized users can delete their own data. 2. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests manipulating the 'ids' parameter. 3. Monitor logs for unusual deletion activity or anomalous access patterns targeting the vulnerable endpoint. 4. If possible, disable or restrict the affected delete functionality until a vendor patch or official fix is available. 5. Conduct a thorough audit of user data integrity and backups to enable recovery in case of unauthorized deletions. 6. Engage with the vendor or community to push for an official patch or mitigation guidance. 7. Educate development and security teams about the vulnerability to ensure rapid response to exploitation attempts. 8. Consider network segmentation to limit exposure of the mall-swarm application to untrusted networks. 9. Review and update incident response plans to include scenarios involving unauthorized data deletion.
