CVE-2026-108622 jeecgboot CVE debrief

Who should care

System administrators and security teams responsible for JeecgBoot installations should assess their exposure and implement necessary mitigations. They should verify the version of JeecgBoot being used, restrict access to the /sys/log/list endpoint and the SysLogController delete handler, and implement proper authorization checks for log deletion. Additionally, they should monitor for any suspicious log deletion activities and review compensating controls

Why it matters

CVE-2026-108622 is a medium-severity vulnerability in JeecgBoot that allows authenticated users to delete audit logs. Defenders should verify and remediate this vulnerability, especially in systems where log integrity is crucial. The exact scope of affected systems and versions requires further verification from official sources.

• Potential log tampering by low-privileged users.
• Loss of audit log integrity and accountability.
• Difficulty in tracing malicious activities due to deleted logs.
• Potential compliance issues due to log deletion.

Technical summary

The vulnerability exists in the SysLogController delete handler of JeecgBoot through 3.9.5. This handler lacks proper authorization, allowing any authenticated user to delete audit log entries. Attackers can exploit this by obtaining log IDs from the /sys/log/list endpoint and then deleting specific sys_log records. This could lead to potential log tampering by low-privileged users, loss of audit log integrity and accountability, and difficulty in tracing malicious activities due to deleted logs. Defenders should prioritize verifying and remediating this vulnerability, especially in systems where log integrity is crucial.

Defensive priority

Defenders should prioritize verifying and remediating this vulnerability, especially in systems where log integrity is crucial.

Recommended defensive actions

• Verify the version of JeecgBoot being used and assess if it is vulnerable.
• Restrict access to the /sys/log/list endpoint and the SysLogController delete handler.
• Implement proper authorization checks for log deletion.
• Monitor for any suspicious log deletion activities.
• 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.

Evidence notes

The CVE record and NVD entry provide details about the vulnerability in JeecgBoot through 3.9.5. The vulnerability exists in the SysLogController delete handler, allowing any authenticated user to delete audit log entries. However, the exact scope of affected systems and versions requires further verification from official sources. Defenders should verify the version of JeecgBoot being used, assess if it is vulnerable, and implement necessary mitigations. They should also monitor for any suspicious log deletion activities and review
