CVE-2026-2076 is an improper authorization vulnerability found in the yeqifu warehouse software, specifically within the User Management Endpoint's addUser, updateUser, and deleteUser functions located in UserController.java. The vulnerability allows an attacker with limited privileges to remotely perform unauthorized user management operations, such as adding, modifying, or deleting user accounts, bypassing intended authorization controls. This flaw arises from insufficient verification of the attacker's permissions before executing sensitive user management actions. The vulnerability affects the codebase up to commit aaf29962ba407d22d991781de28796ee7b4670e4, but due to the product's continuous delivery and rolling release model, no specific version numbers or patches have been published yet. The CVSS 4.0 base score of 5.3 reflects a medium severity level, with the vector indicating network attack vector, low attack complexity, no privileges required beyond limited user rights, and no user interaction needed. The vulnerability impacts confidentiality, integrity, and availability to a limited extent, as unauthorized user account manipulation can lead to privilege escalation or denial of service. Although no confirmed exploits are currently observed in the wild, publicly available exploit code increases the likelihood of exploitation attempts. The vendor has been notified but has not yet responded or issued a fix. Organizations using yeqifu warehouse should be aware of the risk posed by this vulnerability, especially in environments where user management controls are critical for security.

For European organizations, this vulnerability poses a moderate risk primarily through unauthorized manipulation of user accounts within the yeqifu warehouse system. Attackers exploiting this flaw could create or delete user accounts, potentially escalating privileges or disrupting operations by removing legitimate users. This could lead to unauthorized data access, modification, or denial of service conditions impacting business continuity. Organizations relying on yeqifu warehouse for critical inventory or warehouse management functions may face operational disruptions. The remote exploitability and lack of required user interaction increase the threat level, especially in environments where network access to the affected endpoints is not tightly controlled. The absence of a vendor patch or clear remediation timeline further elevates risk, necessitating immediate compensating controls. European entities in sectors such as manufacturing, logistics, and supply chain management using this software are particularly vulnerable. Additionally, regulatory compliance frameworks in Europe, such as GDPR, may be impacted if unauthorized access leads to personal data breaches.

1. Immediately restrict network access to the User Management Endpoint by implementing firewall rules or network segmentation to limit exposure only to trusted administrators. 2. Implement additional application-layer authorization checks to enforce strict role-based access control (RBAC) on addUser, updateUser, and deleteUser functions, ensuring only fully authorized users can perform these actions. 3. Monitor logs and audit trails for unusual user management activities, such as unexpected account creations or deletions, and establish alerting mechanisms. 4. Where possible, enforce multi-factor authentication (MFA) for all users with access to user management functions to reduce risk of compromised credentials. 5. Engage with the vendor or community to track patch releases or updates addressing this vulnerability and plan prompt deployment once available. 6. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious API calls targeting user management endpoints. 7. Conduct internal security reviews and penetration testing focused on authorization controls within the yeqifu warehouse environment. 8. Educate administrators on the risks of this vulnerability and best practices for secure user management until a vendor patch is released.
