CVE-2025-69224

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below of the Python HTTP parser may allow a request smuggling attack with the presence of non-ASCII characters. If a pure Python version of AIOHTTP is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. This issue is fixed in version 3.13.3.

Summary		(es) AIOHTTP es un framework asíncrono de cliente/servidor HTTP para asyncio y Python. Las versiones 3.13.2 e inferiores del analizador HTTP de Python pueden permitir un ataque de contrabando de solicitudes con la presencia de caracteres no ASCII. Si se instala una versión de AIOHTTP puramente en Python (es decir, sin las extensiones C habituales) o se habilita AIOHTTP_NO_EXTENSIONS, entonces un atacante podría ejecutar un ataque de contrabando de solicitudes para eludir ciertos firewalls o protecciones de proxy. Este problema está solucionado en la versión 3.13.3.
