KubeEdge CloudCore lets anyone fake node upgrade results

CVE-2026-82473 · published 5 days ago
Summary

The CloudCore component of KubeEdge (versions up to 1.23.1) accepts status reports about node upgrades without checking who sent them. An attacker who can reach the server on port 10002 could falsely report that upgrades succeeded or failed, confusing the system and preventing future upgrades. Protect the server with proper access controls or upgrade to a version that requires authentication for these reports.
