Описание

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, multiple Host headers were allowed in aiohttp. This issue has been patched in version 3.13.4.

A flaw was found in aiohttp, an asynchronous HTTP client/server framework for Python. This vulnerability allows a remote attacker to send multiple Host headers in a single request. This can lead to unexpected behavior, potentially bypassing security controls or causing cache poisoning, which may result in integrity issues.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
