AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. In versions 3.13.2 and below, reading multiple invalid cookies can lead to a logging storm. If the cookies attribute is accessed in an application, then an attacker may be able to trigger a storm of warning-level logs using a specially crafted Cookie header. This issue is fixed in 3.13.3.

AIOHTTP es un framework cliente/servidor HTTP asíncrono para asyncio y Python. En las versiones 3.13.2 e inferiores, la lectura de múltiples cookies inválidas puede provocar una tormenta de registros. Si se accede al atributo cookies en una aplicación, entonces un atacante podría ser capaz de desencadenar una tormenta de registros de nivel de advertencia utilizando un encabezado Cookie especialmente diseñado. Este problema se ha corregido en la versión 3.13.3.
