Critical (9.9). EPSS 0.3% chance of exploitation in the next 30 days. Fixed in github.com/fission/fission 1.24.0.
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, Fission's Container Executor path lets a tenant supply Function.spec.podspec directly; the executor merges it into the executor-built podspec and creates a Deployment whose pods run the user's container image. This issue has been patched in version 1.24.0.
