CVE-2026-46612 — HIGH (8.8)

Vulnerability Description

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.
