CVE-2026-49823

Summary : CVE-2026-49823 affects Fission (Kubernetes-native serverless framework). Before version 1.24.0, the PackageRef.Namespace in a Fission Function spec was not validated by the admission webhook (unlike Secret/ConfigMap). This allowed cross-namespace access via an unvalidated Package refere...

CVE-2026-49823 Fission: Cross-namespace Package read via unvalidated PackageRef in Function admission webhook

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 Fission Function spec carries three reference types — Secret, ConfigMap, and Package. The first two were namespace-validated by...
