restbed through 5.0.0 Denial of Service via Unbounded Header Buffering
restbed through 5.0.0 buffers HTTP request headers without enforcing a maximum size limit, allowing remote unauthenticated attackers to exhaust server memory. Attackers can open TCP connections and stream bytes indefinitely without sending the header delimiter, forcing the server to allocate unbounded heap memory until the process is killed.
