Fission: Cross-namespace event leakage via KubernetesWatchTrigger allows persistent tenant surveillance

Description

Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes. Prior to version 1.24.0, a low-privilege developer who could create a KubernetesWatchTrigger (KWT) in their own namespace was able to establish a persistent surveillance channel over any other namespace. This issue has been patched in version 1.24.0.
