Several endpoints including /devicemodels, /rules, /ruleendpoints, /offlinemigration in the Cloud Admissioncontroller may be susceptible to a DoS attack if an HTTP request containing a very large Body is sent to it.
Only an authenticated user can cause this issue. It will be affected when users deploy a Cloud Admissioncontroller. The consequence of the exhaustion is that the Cloud Admissioncontroller will be in denial of service.
This bug has been fixed in Kubeedge 1.11.1, 1.10.2, 1.9.4. Users should update to these versions to resolve the issue.
At the time of writing, no workaround exists.
