Fission: Cross-namespace Environment reference in Package allows build-time command execution and SA token exfiltration
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 buildermgr controller processed Package CRDs without verifying that Package.spec.environment.namespace matched Package.metadata.namespace. This issue has been patched in version 1.24.0.
