CVE-2026-2107 is an improper authorization vulnerability found in the yeqifu warehouse software, specifically within the Log Info Handler component's functions: loadAllLoginfo, deleteLoginfo, and batchDeleteLoginfo. These functions are implemented in the LoginfoController.java file and are responsible for managing log information. The vulnerability allows remote attackers to bypass authorization controls, enabling them to load or delete log entries without proper permissions. This can compromise the integrity and availability of log data, which is critical for auditing, forensic analysis, and operational monitoring. The vulnerability requires no user interaction and no prior authentication, making exploitation relatively straightforward over the network. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the moderate impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required. The product does not use versioning, so it is difficult to determine which versions are unaffected. The vendor has not responded to early reports, and no patches or fixes are currently available. Although no active exploits have been observed in the wild, the public disclosure of exploit information increases the risk of exploitation by threat actors.

For European organizations, this vulnerability poses a risk to the integrity and availability of critical log data within yeqifu warehouse deployments. Unauthorized deletion or manipulation of logs can hinder incident detection, forensic investigations, and compliance with regulatory requirements such as GDPR, which mandates secure and reliable logging for data processing activities. Attackers exploiting this flaw could cover their tracks by deleting logs or gain insights into system operations by loading log information without authorization. This could facilitate further attacks or data breaches. Organizations relying on yeqifu warehouse for inventory, warehouse management, or operational data could face operational disruptions or compliance violations. The lack of vendor response and absence of patches increases exposure duration, necessitating proactive mitigation. The remote and unauthenticated nature of the exploit means attackers can attempt exploitation from outside the network perimeter, increasing risk especially for internet-facing deployments.

1. Implement network-level access controls to restrict access to the yeqifu warehouse application, limiting it to trusted internal IP ranges or VPN connections. 2. Deploy web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the vulnerable Log Info Handler endpoints. 3. Monitor application logs and network traffic for unusual access patterns to the loadAllLoginfo, deleteLoginfo, and batchDeleteLoginfo functions. 4. If possible, apply custom authorization checks or patches at the application layer to enforce proper access control until an official fix is released. 5. Isolate the yeqifu warehouse environment from critical systems to minimize impact in case of exploitation. 6. Engage with the vendor or community to track any forthcoming patches or updates. 7. Conduct regular security assessments and penetration tests focusing on authorization controls in the warehouse application. 8. Educate operational teams about the risk and signs of exploitation to enable rapid detection and response.
