CVE-2026-108632 jeecgboot CVE debrief

Who should care

Defenders and administrators of systems using JeecgBoot, especially those with low-privileged user access, should assess exposure and prioritize remediation. They should verify the version of JeecgBoot being used, assess if it is vulnerable, and implement compensating controls for exposed systems while remediation is scheduled and verified.

Why it matters

CVE-2026-108632 is a missing authorization vulnerability in JeecgBoot through 3.9.5 that allows low-privileged attackers to read department permission records. Defenders should prioritize verifying and remediating this vulnerability, especially in systems where low-privileged users have access to sensitive information. The exact scope of affected systems and versions requires further verification from official sources.

• Potential unauthorized access to sensitive department permission records.
• Increased risk of data breaches due to low-privileged user exploitation.
• Need for verification of affected versions and systems.
• Priority for remediation and compensating controls.

Technical summary

The vulnerability exists in the SysDepartPermissionController queryById handler of JeecgBoot through 3.9.5. This handler fails to properly authorize requests, allowing any authenticated user to read department permission records by requesting GET /sys/sysDepartPermission/queryById with arbitrary ids. This allows low-privileged attackers to retrieve depart_id, permission_id, and data_rule_ids for any department, potentially leading to unauthorized access to sensitive department permission records and increased risk of data breaches.

Defensive priority

Defenders should prioritize verifying and remediating this vulnerability, especially in systems where low-privileged users have access to sensitive information.

Recommended defensive actions

• Verify the version of JeecgBoot being used and assess if it is vulnerable.
• Restrict access to the SysDepartPermissionController queryById handler to authorized users only.
• Monitor for any suspicious activity related to department permission records.
• 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 about the vulnerability in JeecgBoot through 3.9.5. However, the exact scope of affected systems and versions requires further verification from the official sources. Defenders should verify the version of JeecgBoot being used, assess if it is vulnerable, and prioritize remediation, especially in systems where low-privileged users have access to sensitive information.
