CVE-2022-36035

Kubernetes workload injection via namespace path traversal

Published Aug 31, 2022 · Updated Apr 23, 2025

Path traversal in Flux CLI before 0.32.0 allows local users to replace Kubernetes deployment content through a crafted namespace. The root command accepted the --namespace flag and FLUX_SYSTEM_NAMESPACE value without DNS-label validation, allowing traversal elements to redirect generated deployment paths. Exploitation requires another application sharing the shell environment and a subsequent Flux CLI deployment, which can install attacker-chosen content in the target cluster.
