This allows a caller authorized for one namespace to bypass that namespace's limits/policies by setting the embedded start request's namespace to a different namespace. The workflow is still created in the outer (authorized) namespace; only validation/gating is performed under the wrong namespace context.\nThis issue affects Temporal: from 1.24.0 through 1.29.1.
