CVE-2026-2860 identifies an improper authorization vulnerability in the feng_ha_ha ssm-erp product, specifically within an unknown function of the EmployeeController.java file. This vulnerability allows remote attackers to bypass authorization checks, potentially granting unauthorized access to sensitive employee data or ERP functionalities. The product is distributed under two different names and follows a rolling release model, which means that traditional versioning and patching mechanisms are not straightforward, complicating vulnerability management. The vulnerability was reported early to the project maintainers, but no response or patch has been issued to date. The CVSS 4.0 vector indicates the attack can be performed remotely over the network without user interaction or elevated privileges, with low complexity and partial impact on confidentiality, integrity, and availability. The lack of authentication requirements and the ability to exploit remotely increase the risk of unauthorized data access or manipulation. Since the exploit details have been publicly disclosed, the threat of exploitation is heightened, although no confirmed exploits in the wild have been reported yet. The ERP system’s role in managing critical business and employee data means that exploitation could have significant operational and compliance consequences.

The improper authorization vulnerability could allow attackers to gain unauthorized access to employee data or ERP system functions, potentially leading to data breaches, unauthorized modifications, or disruption of business processes. This can result in loss of confidentiality and integrity of sensitive information, including personal employee details and business-critical data. Organizations relying on this ERP system may face operational disruptions, regulatory compliance violations, and reputational damage. Since the vulnerability can be exploited remotely without user interaction or elevated privileges, attackers can launch attacks at scale, increasing the risk of widespread compromise. The absence of a vendor patch and the rolling release model complicate timely remediation, prolonging exposure. Industries with high reliance on ERP systems for employee and resource management, such as manufacturing, retail, and services, are particularly vulnerable. The impact extends to supply chain partners and customers if sensitive data is leaked or manipulated.

Given the absence of an official patch, organizations should implement compensating controls immediately. These include restricting network access to the ERP system by implementing strict firewall rules and network segmentation to limit exposure to trusted IP addresses only. Conduct thorough access reviews and tighten authorization policies within the ERP, ensuring least privilege principles are enforced. Enable detailed logging and monitoring of all access to the EmployeeController and related modules to detect anomalous or unauthorized activities early. Consider deploying Web Application Firewalls (WAFs) with custom rules to block suspicious requests targeting the vulnerable endpoints. Engage in proactive threat hunting for indicators of compromise related to this vulnerability. Coordinate with the vendor or community for updates and patches, and prepare for rapid deployment once available. Additionally, educate internal teams about the risk and encourage vigilance against potential exploitation attempts. Finally, maintain regular backups of critical ERP data to enable recovery in case of compromise.
