CVE-2026-2077 is an improper authorization vulnerability found in the yeqifu warehouse software, specifically in the Role Management Handler component within the RoleController.java file. The vulnerability affects the functions addRole, updateRole, and deleteRole, which handle role assignments and modifications. Due to insufficient authorization checks, an attacker with limited privileges can remotely invoke these functions to manipulate roles improperly, potentially escalating privileges or disrupting role-based access controls. The vulnerability is exploitable without user interaction and does not require authentication beyond limited privileges, increasing its risk. The affected version is identified by a commit hash (aaf29962ba407d22d991781de28796ee7b4670e4), and the product lacks versioning, making it difficult to determine the full scope of affected deployments or to track patched versions. The vulnerability was responsibly disclosed to the vendor, but no patch or official response has been provided yet. The CVSS v4.0 score is 5.3 (medium severity), reflecting network attack vector, low attack complexity, no user interaction, and limited impact on confidentiality, integrity, and availability. No known exploits have been reported in the wild, but public disclosure increases the likelihood of exploitation attempts. This vulnerability poses a significant risk to organizations relying on yeqifu warehouse for role-based access control, as unauthorized role manipulation can lead to privilege escalation and unauthorized access to sensitive functions or data.

The improper authorization vulnerability in yeqifu warehouse can lead to unauthorized role manipulation, allowing attackers to escalate privileges or alter access controls within the system. This can compromise the confidentiality, integrity, and availability of sensitive data and system functions managed by role assignments. Organizations using this software may face insider-like attacks from low-privileged users or remote attackers who can exploit this flaw to gain unauthorized administrative capabilities. This could result in data breaches, unauthorized data modification, or disruption of business-critical operations. The lack of vendor response and absence of patches increases exposure time, raising the risk of exploitation. Since the vulnerability affects role management, it undermines the foundational security model of the affected system, potentially allowing attackers to bypass security policies. The medium CVSS score reflects moderate impact, but the real-world consequences depend on the deployment context and the sensitivity of the roles managed by the affected component.

1. Immediately audit and restrict access to the Role Management Handler functions (addRole, updateRole, deleteRole) to trusted administrators only, minimizing the number of users with role modification privileges. 2. Implement additional access control checks at the application or network level (e.g., web application firewall rules) to block unauthorized requests targeting the vulnerable endpoints. 3. Monitor logs for unusual or unauthorized role changes and establish alerting for suspicious activities related to role management. 4. If possible, apply custom patches or code-level fixes to enforce proper authorization checks in the affected functions until an official patch is released. 5. Isolate or segment the yeqifu warehouse deployment to limit exposure to untrusted networks or users. 6. Engage with the vendor or community to track patch releases and apply updates promptly once available. 7. Consider deploying compensating controls such as multi-factor authentication for administrative access and enhanced session monitoring. 8. Conduct a thorough security review of role management and access control mechanisms in the environment to identify and remediate any other potential weaknesses.
