Flux Operator
Monthly
Flux Operator versions 0.36.0 through 0.39.x contain an authentication bypass in the Web UI that allows authenticated users to escalate privileges and execute API requests with the operator's service account permissions. The vulnerability affects deployments where OIDC providers issue incomplete token claims or custom CEL expressions evaluate to empty values, bypassing Kubernetes RBAC impersonation controls. Cluster administrators running affected Flux Operator versions should upgrade to 0.40.0 or later.
