CVE-2026-67297 is a resource-exhaustion vulnerability in FreeRDP before version 3.29.0. When processing HTTP responses using Transfer-Encoding: chunked in http_response_recv_body(), FreeRDP does not enforce RESPONSE_SIZE_LIMIT. A malicious RD Gateway can therefore deliver an oversized chunked response body that is accepted beyond the configured response-size bound.
