CVE-2026-2106 is an improper authorization vulnerability found in the yeqifu warehouse software, specifically within the Notice Management component's controller functions: addNotice, updateNotice, deleteNotice, and batchDeleteNotice. These functions reside in the NoticeController.java file and are responsible for managing notices within the system. The flaw allows an attacker with low privileges to remotely invoke these functions without proper authorization checks, enabling unauthorized creation, modification, or deletion of notices. This could lead to unauthorized information disclosure, alteration of critical notices, or denial of service through notice manipulation. The vulnerability is exploitable remotely without user interaction, increasing its risk profile. The product uses continuous delivery with rolling releases, complicating identification of affected versions and patch availability. The vendor has been notified but has not yet responded or issued fixes. The CVSS 4.0 score of 5.3 reflects medium severity, considering the low attack complexity but limited scope and impact. No known exploits have been observed in the wild, but public disclosure may prompt attackers to develop exploits.

For European organizations using yeqifu warehouse, this vulnerability could allow unauthorized personnel to manipulate notice data, potentially leading to misinformation, disruption of internal communications, or exposure of sensitive operational details. The integrity and confidentiality of notice information could be compromised, affecting decision-making processes and operational security. In regulated industries, unauthorized data manipulation could lead to compliance violations. The remote exploitability without user interaction increases the risk of automated attacks. While availability impact is limited, the trustworthiness of the system is undermined. Organizations relying on this software for critical warehouse or supply chain management functions may face operational disruptions or reputational damage if exploited.

Given the lack of vendor response and patch availability, European organizations should implement compensating controls immediately. These include restricting network access to the yeqifu warehouse Notice Management interfaces via firewalls or network segmentation to trusted administrators only. Implement strict access control policies and monitor logs for unauthorized access attempts to notice management functions. Employ Web Application Firewalls (WAFs) with custom rules to detect and block unauthorized API calls targeting the affected endpoints. Conduct regular audits of notice data integrity to detect unauthorized changes. If feasible, consider temporarily disabling or restricting notice management features until a patch is available. Engage with the vendor for updates and monitor security advisories closely. Additionally, integrate this vulnerability into incident response plans to ensure rapid detection and mitigation if exploitation is suspected.
