Fission versions prior to 1.24.0 contain a security context validation bypass in Environment runtime and builder container fields. A tenant with RBAC permissions to create or update environments.fission.io objects can specify privileged containers, enable allowPrivilegeEscalation, or request dangerous Linux capabilities in the Fission function or builder namespace. These containers are then scheduled under the executor's high-privilege service account. This breaks the intended isolation boundary for tenant-supplied workloads and can permit escalation from a low-privileged tenant role to execution with excessive Kubernetes and node-level privileges.
