HIGHCVSS v4 8.7Vulnerability

CVE-2026-128132

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, the WebSocket reader continues parsing frames already received after the receive queue pauses the transport, and empty messages are not counted toward the queue size. With permessage-deflate, one read of compressed frames can add many megabytes of decompressed messages to the receive queue. A remote peer can send many small or compressed messages faster than the application consumes them and cause excessive memory use in a server or client. This issue is fixed in version 3.14.4.
