CVE-2026-46612: Fission StorageSvc /v1/archive endpoint exposes unauthenticated CRUD over all function archives

May 21, 2026 (updated June 10, 2026)

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.
