CVSS 3.1
6.8 mediumCVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:NCVE-2025-46599
Medium (6.8). EPSS 0.5% chance of exploitation in the next 30 days. Fixed in github.com/k3s-io/k3s 1.32.4-rc1.
CNCF K3s 1.32 before 1.32.4-rc1+k3s1 has a Kubernetes kubelet configuration change with the unintended consequence that, in some situations, ReadOnlyPort is set to 10255. For example, the default behavior of a K3s online installation might allow unauthenticated access to this port, exposing credentials.
