CVE-2026-108635 jeecgboot CVE debrief

Who should care

Defenders and administrators of systems using JeecgBoot through 3.9.5 should assess exposure and prioritize verification of access controls to the affected endpoint, especially in environments where low-privileged users have access to department staff information.

Why it matters

CVE-2026-108635 is a missing authorization vulnerability in JeecgBoot through 3.9.5 that allows authenticated users to list department staff. Defenders should prioritize verifying and limiting access to the affected endpoint, especially in systems where low-privileged users have access to department staff information. The corpus does not establish versions beyond 3.9.5, exploitation, impact, or remediation, which require verification from the supplied official sources.

• Potential enumeration of departId values by low-privileged attackers
• Unauthorized retrieval of staff names, avatars, posts, and mobile and telephone numbers
• Exposure of contacts marked hidden
• Verification of access controls to the GET /sys/sysDepart/getDepartmentHead endpoint

Technical summary

The vulnerability exists in the SysDepartController of JeecgBoot through 3.9.5, specifically in the GET /sys/sysDepart/getDepartmentHead endpoint. This endpoint allows any authenticated user to list department staff without proper authorization, enabling low-privileged attackers to enumerate departId values and retrieve sensitive staff information. Defenders should prioritize verifying and limiting access to the affected endpoint, especially in systems where low-privileged users have access to department staff information. The CVE record and NVD entry provide details on the vulnerability. However, the corpus does not establish versions beyond 3.9.5, exploitation, impact, or remediation, which require  

Defensive priority

Defenders should prioritize verifying and limiting access to the affected endpoint, especially in systems where low-privileged users have access to department staff information.

Recommended defensive actions

• Verify and limit access to the GET /sys/sysDepart/getDepartmentHead endpoint
• Restrict enumeration of departId values
• Monitor for unauthorized access to department staff information
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide details on the vulnerability. However, the corpus does not establish versions beyond 3.9.5, exploitation, impact, or remediation, which require verification from the supplied official sources.
