CVE-2026-108626 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 mitigation. They should verify the version of JeecgBoot being used and restrict access to the affected endpoint. Implementing proper authorization checks and monitoring for suspicious activity is crucial to prevent potential disclosure of sensitive message content and exposure of receiver addresses.

Why it matters

CVE-2026-108626 is a missing authorization vulnerability in JeecgBoot through 3.9.5 that allows low-privileged authenticated users to read any message push record. Defenders should prioritize verifying and mitigating this vulnerability, especially in systems where low-privileged users have access to sensitive information. The impact includes potential disclosure of sensitive message content and exposure of receiver addresses. Remediation efforts should focus on restricting access to the affected endpoint and implementing proper authorization checks.

• Potential disclosure of sensitive message content.
• Potential exposure of receiver addresses of other users.
• Verification of affected versions and system configurations is required.
• Prioritization of remediation efforts based on system risk assessments.

Technical summary

The SysMessageController queryById handler in JeecgBoot through 3.9.5 does not properly authorize access to message push records. This allows low-privileged authenticated users to read any message push record by supplying arbitrary record IDs to the GET /sys/message/sysMessage/queryById endpoint. The vulnerability impacts systems using JeecgBoot, especially those with low-privileged user access, potentially disclosing message content and receiver addresses of other users. Defenders should prioritize verifying and mitigating this vulnerability.

Defensive priority

Defenders should prioritize verifying and mitigating 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 (3.9.5 or earlier).
• Restrict access to the GET /sys/message/sysMessage/queryById endpoint to authorized users.
• Implement proper authorization checks for sensitive information disclosure.
• Monitor for any suspicious activity related to message push 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.

Evidence notes

The CVE record and source references indicate a missing authorization vulnerability in JeecgBoot through 3.9.5. However, details about the affected versions, exploitation, and impact are limited. Defenders should verify the version of JeecgBoot being used and assess if it is vulnerable (3.9.5 or earlier). Limited source information is available; explicit evidence is needed to confirm exploitation and full impact.
