Summary

Fission is a serverless framework, Kubernetes-native, that prior to version 1.23.0 did not require authentication or authorization for CRUD operations on archives in the storagesvc component. This allowed unauthorized users to access archives belonging to other users.

Risk Assessment

The lack of proper security mechanisms in storagesvc poses a risk of unauthorized data access, which could lead to information leaks and violations of user privacy.

Recommendation

It is recommended to upgrade to version 1.23.0 or later to secure the storagesvc component against unauthorized access.

Original NVD description (English source)

Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes. Prior to version 1.23.0, the Fission storagesvc component registers archive CRUD handlers (/v1/archive GET / POST / DELETE and /v1/archives list) directly on its HTTP router without performing any authentication or authorization. Any caller able to reach the storagesvc ClusterIP — including any other workload in the same Kubernetes cluster — could enumerate archive IDs, download archives belonging to other tenants, upload arbitrary archive content, and delete archives. This issue has been patched in version 1.23.0.
