CVE-2026-2076 identifies an improper authorization vulnerability in the yeqifu warehouse software, specifically within the User Management Endpoint implemented in the UserController.java file. The affected functions—addUser, updateUser, and deleteUser—lack sufficient authorization controls, allowing an attacker with limited privileges to remotely manipulate user accounts. This flaw arises from inadequate verification of the attacker's permissions before executing critical user management operations. The vulnerability is present in the codebase up to commit aaf29962ba407d22d991781de28796ee7b4670e4. Due to the product's continuous delivery model with rolling releases, specific version details for affected or patched releases are unavailable. The vulnerability has a CVSS 4.0 base score of 5.3, indicating medium severity, with an attack vector of network (remote), low attack complexity, no required privileges, and no user interaction. The impact vector components indicate limited confidentiality, integrity, and availability impacts but still significant due to unauthorized user management capabilities. Although no known exploits are currently active in the wild, a public exploit is available, increasing the risk of exploitation. The vendor has been notified but has not yet responded or released a patch. This vulnerability could be leveraged to escalate privileges, create unauthorized accounts, or disrupt user management processes, potentially compromising the overall security posture of affected deployments.

The improper authorization vulnerability in yeqifu warehouse's user management functions can lead to unauthorized creation, modification, or deletion of user accounts. This undermines the integrity and confidentiality of user data and can facilitate privilege escalation or persistent unauthorized access. Organizations relying on yeqifu warehouse for critical operations risk exposure to insider threats or external attackers who gain limited access but can exploit this flaw to expand control. The availability of user management services may also be disrupted if attackers delete or alter accounts maliciously. Given the remote exploitability without user interaction or elevated privileges, the threat can propagate rapidly in exposed environments. The lack of vendor response and patch availability increases the window of exposure. This vulnerability could impact compliance with access control and identity management policies, potentially leading to regulatory and reputational consequences.

Organizations should immediately audit and restrict access to the User Management Endpoint in yeqifu warehouse, ensuring only fully trusted and authenticated administrators have permissions to invoke addUser, updateUser, and deleteUser functions. Implement network-level access controls such as IP whitelisting or VPN requirements to limit exposure. Employ Web Application Firewalls (WAFs) to detect and block anomalous requests targeting user management APIs. Monitor logs for unusual user account activities, including unexpected creations, modifications, or deletions. If possible, temporarily disable remote user management features until a vendor patch is available. Engage in code review or implement custom authorization checks as a temporary mitigation if source code access is available. Maintain up-to-date backups of user data and configuration to enable recovery from malicious changes. Stay alert for vendor updates or community patches and apply them promptly once released. Consider isolating the yeqifu warehouse deployment in segmented network zones to reduce attack surface.
