"text": "## Details\n\nflagd exposes OFREP (`/ofrep/v1/evaluate/...`) and gRPC (`evaluation.v1`, `evaluation.v2`) endpoints for feature flag evaluation. These endpoints are designed to be publicly accessible by client applications.\n\nThe evaluation context included in request payloads is read into memory without any size restriction. An attacker can send a single HTTP request with an arbitrarily large body, causing flagd to allocate a corresponding amount of memory. This leads to immediate memory exhaustion and process termination (e.g., OOMKill in Kubernetes environments).\n\nflagd does not natively enforce authentication on its evaluation endpoints.
