CVE-2026-2078 is an improper authorization vulnerability found in the yeqifu warehouse product, specifically within the PermissionController.java file's addPermission, updatePermission, and deletePermission functions. These functions handle permission management, and the flaw allows an attacker to remotely manipulate authorization settings without proper privilege checks. The vulnerability arises due to insufficient validation of the requester's rights before modifying permission data, leading to unauthorized changes. The affected version is identified by a specific commit hash (aaf29962ba407d22d991781de28796ee7b4670e4), but due to the product's rolling release model, multiple versions may be impacted. The CVSS 4.0 score is 5.3 (medium), reflecting network attack vector, low attack complexity, no privileges required, no user interaction, and limited impact on confidentiality, integrity, and availability. The exploit is publicly available, increasing the risk of exploitation despite no known widespread attacks yet. The vendor has been notified but has not issued a patch or official response. This vulnerability can lead to unauthorized privilege escalation or unauthorized permission changes, potentially compromising system security and data integrity within affected environments.

For European organizations, this vulnerability poses a risk of unauthorized access and privilege escalation within systems using yeqifu warehouse for permission management. Attackers could remotely alter permissions, potentially granting themselves or others elevated rights, leading to data exposure, unauthorized modifications, or disruption of services. This could impact confidentiality by exposing sensitive data, integrity by allowing unauthorized changes, and availability if critical permissions are revoked or misconfigured. Organizations in sectors with strict regulatory requirements (e.g., finance, healthcare, government) may face compliance violations and reputational damage. The lack of vendor response and public exploit availability increases the urgency to address the issue proactively. The rolling release nature complicates patch management, requiring continuous vigilance. Overall, the threat could disrupt business operations and compromise sensitive information if exploited.

1. Immediately restrict access to the permission management functions (addPermission, updatePermission, deletePermission) to only highly trusted administrators using network segmentation and access control lists. 2. Implement enhanced monitoring and logging for all permission changes to detect suspicious or unauthorized modifications promptly. 3. Conduct a thorough audit of current permissions to identify and remediate any unauthorized changes that may have occurred. 4. Apply strict input validation and enforce role-based access controls at the application layer as a temporary mitigation if source code modification is possible. 5. Engage with the yeqifu project or community to track patch releases or security advisories and apply updates as soon as they become available. 6. Consider deploying Web Application Firewalls (WAFs) with custom rules to block suspicious requests targeting permission management endpoints. 7. Educate administrators about the vulnerability and the importance of cautious permission management and monitoring. 8. For critical environments, consider isolating or temporarily disabling the affected components until a patch is available.
