Fission versions prior to 1.24.0
Description
Fission is an open-source, Kubernetes-native serverless framework used for deploying functions and applications on Kubernetes. The Container Executor path allows a tenant to directly supply
Function.spec.podspec, which the executor then merges into the executor-built podspec to create a Deployment. This process can lead to podspec injection, potentially resulting in a node escape.Recommendations
Update to version 1.24.0.
