Authenticated host command execution via PowerShell interpolation
Published Mar 13, 2025 · Updated Mar 13, 2025
Command injection in Kubernetes Kubelet on affected Windows worker releases allows remote authenticated users to execute host commands. The Windows node log query handler interpolates request-derived provider names and match patterns directly into a PowerShell command, allowing subcommand expressions to execute. Exploitation requires permission to query a node's /logs endpoint and enabled node-log querying; successful attacks can read or alter host data.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=<=v1.29.12
- Affected versionversion=v1.30 <=v1.30.8
- Affected versionversion=v1.31 <=v1.31.4
- Affected versionversion=v1.32 <=v1.32.0
