CVE-2026-82473
Attackers can reach CloudCore on port 10002 to mark upgrade jobs as succeeded or failed, deceiving the control plane about node upgrade status and blocking further upgrade scheduling.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
