Description

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, the Secure attribute for a shared cookie is not enforced. An attacker can consequently cause a shared cookie marked Secure to be sent with an unencrypted request. This issue is fixed in version 3.14.4.
