Vulnerability AssessmentAI

Exploitation Exploitation targets the 'files' parameter of the JeecgBoot AI Chat Module in v3.9.2, so the deployment must have the AI Chat feature present and the relevant endpoint reachable by the attacker. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals are mixed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation No vendor-released patch is identified at time of analysis; the only reference is the GitHub issue report (https://github.com/jeecgboot/JeecgBoot/issues/9774), so monitor that thread and the JeecgBoot release notes for a fixed version and upgrade as soon as one is published. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, isolate or restrict network access to any JeecgBoot v3.9.2 deployments, particularly the AI Chat module endpoints, and verify whether the 'files' parameter is exposed to untrusted users. …
