Executive Summary

CVE-2026-108881 is a missing authorization vulnerability in JeecgBoot through version 3.9.5. It affects the getTenantPackInfo handler, allowing any authenticated user to read sensitive information about other tenants by supplying a tenantId and fixed packCode values like superAdmin or accountAdmin. This exposes administrator usernames, real names, phones, and departments.

Detection Guidance

To detect this vulnerability, check if your JeecgBoot instance exposes the /sys/tenant/getTenantPackInfo endpoint. Use curl to send a GET request with a tenantId and packCode like superAdmin to see if it returns sensitive admin data without proper authorization.

Impact Analysis

An attacker with low privileges could exploit this to gather sensitive data about tenant administrators, including personal details like phone numbers and real names. This could lead to further attacks such as social engineering, unauthorized access, or data breaches. The vulnerability allows disclosure of critical information without requiring elevated permissions.

Compliance Impact

This vulnerability likely violates GDPR and HIPAA due to unauthorized access and disclosure of personally identifiable information (PII) and protected health information (PHI). It enables exposure of sensitive user data without consent, which is a direct violation of data protection requirements for confidentiality and access controls.

Mitigation Strategies

Immediately update JeecgBoot to the latest version beyond 3.9.5. If an update is not possible, restrict access to the /sys/tenant/getTenantPackInfo endpoint and implement proper authorization checks to ensure only authorized users can access tenant data.
